Seriously, what is up with the rude jokes and cracks about autistic, or mentally ill people? It's unfair of you to judge people on how their brain functions. I have an autistic brother, don't sit there and joke around about stuff like that to me, because you know it's going to upset me.
Nobody's perfect, but people insist on making fun of people who are at a lesser advantage. Does it make you feel better when you pick on someone who isn't able to fight back? You're pathetic.
