most people i meet think i'm ~ 20-23 yrs old. i am petite and this makes me appear younger as well, i suppose.
of course it's nice to appear younger.
sometimes people patronise me, which is a bit annoying, but for the most part it really doesn't bother me. firstly, because it works in my favour. i am shy when meeting new people, and if people presume i'm younger, there's less expectations, less pressure. secondly, i don't care much if people misjudge me; i know who i am.
