One brother, 33, stupid, 'nuff said.
Growing up, we loved each other, but fought fiercely. I, being the older, had to 'keep him in line' and sad for him, by the time he was big enough to kick my ass, we were too old to behave like that. lol As time passed, we actually became best friends, and his friends became my 'little' brothers as well. I am 'sis' to a LOT of people. lol I still call my brother stupid, not, unintelligent, just stupid in the things he does. As a child it was always thus. He could carry on a philosphical conversation with me, then, turn around and actually trade his car for a stupid camera and 800 bucks.
I don't see him much anymore, nor, do we talk on the phone a lot. Our lives have taken entirely different directions, but, when we do speak, we pick up like we never left off.
As for single children, I can't really comment on it. I guess, it would depend on how you're raised. If you're the only child and a spoiled brat because of that, then, I'd guess, you'd better be happy you don't have to share with another. If, on the other hand, your parents aren't total losers and don't spoil you, don't cater to your whim like you're some kind of miracle, then you're missing out on potentially, one of the greatest things in the world.
I'd like to comment on ninja's response though. I find it sad you feel that way. I, myself, dislike children, have, for the most part, disliked my age mates even when I was a child. I mostly dislike stupidity in the deepest sense of the word. I currently find myself feeling nothing either way toward children. I see so many every day at work, and, I watch parents, and grandparents with them and it struck me, all my life I've been mistaken. It's not the children, whom should be despised, it's the parents. The parents are stupid, they fail to teach/train their children properly. These parents' parents were probably just as ill equipped and ill suited for breeding as their current offspring are. It's a terribly vicious cycle. For me, fun wasn't sitting in front of a television all day, it was being outside, using my imagination, and others' like me to invent games. If unable to be outside, those few age mates that I DID associate with, would gather at one's house, and pull out a dictionary or globe. The games were 'word of the hour':the idea is pick a page at random from the dictionary, drop a penny, the word the penny covered was the word of the hour, define it then use it as often as possible in any sentence any context. Our second game was 'around the world': Spin the globe, close your eyes, stop the globe with your finger and where your finger landed name the capital of that country, then plan a vacation there, what sights to see, break out the encyclopedias and give a brief historical account of that country etc. I feel that if children were encouraged to use THEIR minds and to learn on their own more often, we wouldn't be faced with an ever increasing population of imbeciles. That won't happen, however, as the parents are already imbeciles, and being stupid is like being on welfare, it's a hard cycle to break out of as, each successive generation falls deeper and deeper into the pit.
