@ more than pretty.
Finding out someones address is stalking and dosn't have anything to do with a disability.Writing letters and asking to help with towers to someone he dosn't know isn't a symptom of social shyness either. I am kind of creeped for you now.
I say just forget it but tell your sister not to help anyone with a broken arm put anything in a truck or for that matter a tower. S.O.L.
I say if he isn't asking to do something social that would appeal to a girl then forget it. Oh but maybe she's a nerd and likes building towers? * shurg*
ok enough about that.
and now a simple game.
