A lot of people kiss their pets or non-human animals in general. I find that very weird. I understand that it is a sign of affection but it seems so off. One reason is that I doubt whether animals really understand this. Also it seems to be on a level of intimacy to me that I find weird sharing with a pet. Not necessarily romantically or sexually (that would be even more weird and wrong and probably illegal). But it is still "more". I am not sure whether I can really explain why exactly I find that weird.
Anyway, what is something that is weird to you but not to most other people?
I think many people had happy childhoods, enjoyed family life, and want the same when they're older. Most humans are tribal and often want to be part of a family and, indeed, to add to it.
Personally, I was indifferent to having children throughout my 20s and well into my 30s. My wife was keen, and I wasn't averse to the idea.
As it happens, it was, by an order of magnitude, the best decision I made in my entire life. It completely altered my perception of self, the world, and everything.
