I'm thinking of pulling the blind man's cane out of his hands as I walk by him.
But won't he fall down if you do that?
I don't care, I'm going to do it anyway.
Pulling the old man's cane will likely cause him to fall and get injured. Doing this is rude and disrespectful, so really don't think you should.
Yeah, but this guy is awful and I don't care if he gets hurt.
I do not know what gave you a negative perception of the person, but physically assaulting a handicapped person is inexcusable for any reason and I hope that you will decide not to do that.
