I guess the grossest thing to me ever is when I meet single people and they tell me about how much they really want to be a parent and have kids. I'm like listen up [redacted], you don't even have a career or a significant other, and you're already talking about kids. That's what I hate. If you've got your life in order, have a mate that is great, go ahead procreate.
I just hate when people have shitty lives and then have children and make their lives about their children to make up for the fact that they have shitty lives.
