My daughter has always been really tall and has always looked years older then she is. She just turned 11 but is a foot taller then me and wears a size 9 shoe. Anyway, since she just turned 11 she can show in the 10 and under class because the she was 10 by January 1st. Weel, this past show in her very first class (Huntseat Eq.) she got first out of 7 riders. As she was walking out of the arena she heard a handler tell the rider "Don't be upset you didn't win, that girl is cheating she is way older then 10." She was really really sad about it and I it made me so angry it took everything in my power not to go find that handler and give her a piece of my mind.
Then when I was at the kiosk waiting to look at the Championship pictures (she won Resrved Champion in both Eq. And HP) there was a lady who was there frist looking at the screen in front of us with one fo the girls who were in my daughters class. Not realizing I was behind her, she pointed at my daughters picture and said "I really don't think that girl who won was 10." She didn't say it meanly but still. I leaned over and said nicely, "Hi, I'm her mom and I know she doesn't look it, but she just turned 11 this month." She smiled and apologized and was very nice but it just irked me.
Anyway, I apologize for this long rant and I hope it doesn't come across too complainy. I just wanted to put it out there that sometimes kids in these age classes can look much older then they are. Be careful before you assume someone is cheating. :)
