I'm in year 7 (well,8 really,but this all happend in year 7) a year 9 thought I was in year 8 (though that might be because I have a friend who is in his year & form who I am with a lot and he is like 5'2") and a year 8 thought I was in year 9 (because I knew the 5'2" guy mentioned in oucrestra (?) and I know the year 8 though oucrestra to) and I think thats it.
So really I have Alex to thank (or blame) for all this.
People ALWAYS think I'm older than I actually am. I'm 13 and they think I'm like 16 or so. One time when I was talking one of my best friends commented on how I always acted, looked, and talked like someone wayyyyy older.
