If you've decided not to have children, what are your reasons?

I'm one of those people who never wants kids. I have my reasons and there are many. They're too expensive, I don't have the patience, I can be very irritable, they're messy, I like time to myself, I like the ability to come and go as I please and not have to worry about who's watching the kids, etc, etc. The list goes on. I'm one of those people in the world who should never be a parent.

I definitely want to have children. I know there are some people who do not want them and I can respect that. What bothers me is the people who have no sense or ability to be good parents having 4 or 5 of them and them all being on welfare.

I've decided I don't want to have any kids when I was a teen, and I'm in my early 20s now and I stand by my decision (despite what my mother and sister thinks). My reasons are just as Poison_Girl said--kids being expensive, I'm not always patient, and I enjoy the freedom. I don't really like kids anyway. Not that I would ever want any harm to come to them, or I wouldn't try to help a child if they were in danger, but I just don't like kids. Although I consider myself a kind and caring person, I just don't can't see myself as a parent.
