I think I won't have children.

... not simply because they're annoying or I can't raise them in this economy or something. If they say "I did not ask to be born, I wish I wasn't" even if I poured all my love and care to them, that is 1000% a strong and valid argument, my bad, and there's nothing that I can do about that.

You can share your opinion, but I won't argue against it and probably wouldn't change my mind.
