I've heard quite a few people, both in real life and on Mumsnet, say they don't like spending time with other people's children, only their own, with the general consensus being that kids are annoying, snotty, boring, etc. and only tolerable if they're your own. Since I don't personally feel this way about children, I don't understand why someone would have kids if they feel this way about children.
If you're the kind of person who says they don't like other people's children, have you always felt that way? If so, how did you decide to have children? If not, why did your opinion change? No judgement, just curiosity.
