I'm 14my Mom is 52, my Dad is 63, I have two half brothers who are 30 and 26 years older than me, and a half sister who is 29 years older than me.
I never really told anyone. I had a friend with old parents(I think when she was 13 her Dad was 67 and her Mom was 48....)and people made fun of her, and I totally told them off one day, but I didn't tell them about my parents. :/
People think it's like the weirdest thing in the world sometimes, but I'm a lot less erm....troublemakinger...than them, so HA! Whose parents are awesomer?
