How to Choose Your Friends: Practical Criteria

People are always told to "choose your friends carefully", but rarely told how. In reality most friendships aren't chosen at all — they happen by circumstance: the person sitting next to you, a neighbour, a colleague. The real choosing comes later: who you invest time in, and who stays in the circle of acquaintances.

First Criterion: How You Feel Afterwards

This is the simplest and the most accurate. After two hours with someone, do you feel lighter or heavier? It isn't only about fun — some people are serious and still leave you at ease, and others are funny and leave you tense without your knowing why.

The advantage of this criterion is that it needs no analysis. Don't ask "is this a good person?", a hard question to answer, but "how did I feel?" The body registers this before the mind puts it into words.

Second Criterion: What They Do in Others' Absence

Someone who criticises their friends in front of you will criticise you in front of them. That isn't harsh judgement, it's simple inference: a person who does this has a habit, and habits don't make exceptions.

The reverse holds too: someone who defends an absent person, and declines to dig into details that aren't their business, gives you an indication of how they'll behave when you're the absent one. That's a more reliable indicator than any direct kindness towards you.

Third Criterion: How They Behave When They Don't Need You

The real test of a relationship isn't the crisis but the ordinary stretches. Someone who appears only when they want something and disappears afterwards has a functional relationship with you, not a friendship. Someone who reaches out for no reason — a passing message, a question about something you mentioned before — gives a clearer signal than any occasional heroic gesture.

Notice one small detail: does the person remember what you told them? Remembering is evidence of attention, and attention is the practical form of care.

Fourth Criterion: Can You Disagree?

A friendship that can't take disagreement is fragile however warm it appears. Try expressing a different view on something minor and watch what happens: do they discuss, bristle, or ignore it? Someone who accepts disagreement on small things usually accepts it on large ones.

And the criterion runs both ways. Ask yourself too: am I comfortable being disagreed with? Anyone looking for friends who always agree is looking for an audience, not a relationship.

Criteria People Think Matter and Don't

Having exactly the same interests isn't a requirement; many long friendships exist between people with entirely different tastes. Length of acquaintance also misleads — ten years of surface-level meetings doesn't equal one year of real shared experience. And frequency of contact: someone who sends twenty messages a day isn't necessarily closer than someone who calls monthly with actual substance.

What unites these misleading criteria is that they're all easy to measure, which is why they attract us. The ones that genuinely matter require observation and patience.

Circles: Not Everyone Needs to Be Close

Trying to make every acquaintance a close friend always ends in exhaustion. Time and attention are limited, and dividing them equally among twenty people means nobody gets enough. It's better to think in layers: a very narrow circle of close people, a wider group of friends, and cordial acquaintances.

Organising the circles isn't coldness, it's fairness. Once you know a relationship sits in the second layer, you stop expecting from it what you'd expect from the first, and most of the frustration disappears. Almost all disappointment in relationships comes from expectations aimed at the wrong circle.

When to Reassess an Existing Relationship

Reassessing isn't betrayal. Relationships change, and someone who suited one phase may not suit another. Signs that warrant a pause: hiding good news to avoid the person's reaction, feeling tired before a meeting rather than after, or noticing that every initiative comes from you.

Reassessing doesn't mean cutting off. Most cases resolve by adjusting distance: fewer expectations, less frequency, a quiet shift between layers. That discreet adjustment preserves goodwill and prevents the drain.

Time Is the Only Test That Doesn't Lie

All the criteria above can be misread in a meeting or two. The person may be having a bad day, or an exceptional one. What can't be faked is the pattern over months: who reaches out consistently, who remembers, who shows up when they need nothing.

So the most practical advice is not to rush in either direction. Don't move someone into your closest circle after a fortnight of enthusiasm, and don't write off a relationship over a single episode. Time sorts this more precisely than any analysis.

A Practical Way to Start

If you want to know where your current relationships actually stand, begin with contact rather than analysis. Send a friendship quiz to three people you consider close, and watch not the score but who answered quickly, who engaged, and who ignored it. That observation alone tells you more than any checklist. To go deeper, see the signs of true friendship.
