Personally, in general, I hate kids. Ask any of my friends and they'll tell you that I say it just about every time kids come around; I'm not at all secretive about my hatred for them. Lol. But I'm torn, because every now and again a kid will come along and they'll be absolutely adorable or just really cool.
I feel like the main reason I dislike kids on principle is because parents these days just don't discipline their children like they should (like I think they should, anyway). When kids end up as bratty and arrogant as most are these days, I become incredibly upset by the apparent lack of effort on their parents' part. It just irks me when a parent can't even control their child by the time they hit age 6 or 7. That's supposed to be the time when they're innocent and curious, but instead they're just disrespectful, whiny, and downright insulting to everyone.
Example: when I was in Kindergarten, if I saw a high school student, I'd be intimidated and awestruck just for the fact they were tall and "old". But by the time I got into high school myself, all the little kids (well, most) wanted nothing more than to pick fights and insult me and my classmates to... impress their friends? I guess? I dunno. It just seems wrong to me.
Anyway, random tangent aside, I'd like to have kids someday. But not for a good while. I don't think I'll be settling down with anyone until my low thirties at least. There's just too much I want to do and see that I probably won't be able to if I get into a permanent relationship.
