As Stevie Wonder once said Roses are black, violets are black, everything is black, I can't fucking see. .
I think that we should not joke about things like that!
I don't feel bad for him, he wanted it that way
I am pretty sure that he was born that way. You should not joke about the things that people cannot change about themselves, it is a little hurtful.
I don't care I want to show him it's not a big deal.
Stevie wonder is an amazing musician. You should have some respect and not make fun of him, it reflects poorly on your character.
