Boy/girlfriends at young ages? Simply because that's all that's shown in media. =\ You should all know what I mean. Kids just see all those music videos and everything and they aspire to be just like the people in them. So they grow up too fast and end up getting themselves into more mature situations. There's not really much we can do about it, but that's how it is now. It used to be you started looking into other people at the age of 16... but now people in grade 6 are hooking up. I don't approve of it myself, but maybe because I was sort of sheltered until I moved to Toronto, which is a much bigger city than I had been living in before. =\
Oh, and pregnancy problems aren't really all that much of a worry until one's early 40s/late 50s when the woman is closer to entering menopause. ^_^; My mom had me when she was about 30 and my brother when she was 38. Both of us turned out fine, and we're actually better off than many other children. x.o; (Blah, gifted and the like.)
And no, I've never been in the situation where I like one person and that person likes someone else. I was lucky, because my crush liked me back ._.
