I'm going to flat out ignore a mentally handicapped person
Why are you being so mean to this person?
I was standing in the waiting line, he only came there to try a ride, not playing games as well as expected
It's not nice to do things that hurt a handicapped person's feelings. You should learn to be more considerate.
They should learn to not be handicapped in the first place.
It is hard to understand people who are handicapped but you shouldn't do things that deliberately hurt them. People will think you are a bully.
