i wouldn't be rude about it. but i would just like to hear his answer. he obviously craves attention. and the kind he gets from such things is obviously that of confusion/contempt. so he gave up on positive attention a while back from society. what made him give up on that kind of attention, the kind he should prefer? that is what i'd really be asking him.
but who knows, maybe this guy just puts a shirt on and unplasters those fangs and functions on a completely normal level/leads a full life.
