If we're being "serious", it seems to me that interacting with people is extremely tiring, and full of pitfalls. It has often struck me as possibly being more effort than it was worth.
The way I see it (and in my experience), human beings are, by nature, fundamentally selfish. They will most-of-the-time put their own self-interests first, even if they don't consciously-realise they are doing so.
Hence interactions with people are always something of a battle, for everyone, a fight to avoid being taken advantage of. (And, for that matter, politics is fundamentally about different groups of people fighting to protect their self-interests, in a context where there are huge imbalances of power between groups, and, usually, an unavoidable lack of understanding of why the other groups see things they way they do).
That's been my experience, both with "professional" interactions (in particular with doctors - for my entire life had a rare condition that doctors don't know much about, that took decades of symptoms to get diagnosed - which made it very clear to me that doctors, like other professionals, will, when push-comes-to-shove give their needs priority over yours) and with personal/social ones.
It's always a fight, because the other person will usually put their own self-interests first and foremost. The only exception being when people see the 'other' as an extension of themselves, which is often the case with parents and their children (and not always, even then).
I've found it gets worse with age, as everyone gets increasingly overwhelmed by their own problems and needs and hence becomes still more selfish. Also, on a social level, the same seems to happen when economic conditions get worse.
If you add in the fact that everyone has very different formative experiences, and exists in a different set of circumstances, meaning their interests are going to clash with those around them, it all gets very tiring.
_Especially_ so if you are in a minority of any kind, particularly if it's a disadvantaged one, meaning your interests are particularly likely to conflict with many of those around you.
It's a wonder to me that human societies can function at all, or that any personal relationships last.
The OP should be careful what they wish for, as more friends might turn out to just mean more conflict and more demands. Both on a personal level, as we all age, and on a political level, as the numerous crises in the world continue to worsen, interactions with people are only going to get more stressful and exhausting.
