I'm 14, but I'm not exactly sure how old I look? Lol
People always think I'm older than I am but meh. Probably doesn't help that I am like 5' 9". Ahh I don't know.
The worst thing is my younger sister (by 4 years) is taller than me and looks older, and people constantly mistake her for the older sibling and ask her how uni is going.
NO.
I'm 29 and look early/mid 20s I guess. I still get ID'd every so often, and it really makes me day when that happens ;-)
