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?
Here's something that will probably mark me as weird: I find it strange, even creepy, when people talk, sing, hum, or make any noises to themselves. Some people tell me it helps their concentration, but I can't even envision making any kind of sound when I concentrate.
