I like to go on Yahoo Answers, gives me anonymity (sp?) to give my 2 cents without anyone taking my age into account. And lately I've been answering more relationship questions, even by married people, and it seems I know more then they do! People that are older than me, supposedly wiser. They can't see a red flag when it's there. They think they love someone they've known for a week. So many things taht seem blatantly obvious to me.
A long time ago I asked a question on there about brining your kids up into a certain religion. Naturally I got strong opinions on both sides, but a lot of them assumed I had children, and/or that I was an adult. I told them I was 16 years old, and they said "There's no way you're 16".
That's why I get kind of offended when people mistake me for being younger than I am based on my looks, because inside I have the wisdom of someone who is 40. (not that I want to look 40 either =P)
