I think I laughed at a dude in a wheelchair
Do you just think you laughed at him directly, or did it just look that way at the time?
I really did. It was an accident, I admit it. I also apologised to him.
I'm glad you apologized! You should never laugh at others, especially those with disabilities. Next time, think before you react.
I'm sorry to anyone else I might have laughed to, too. I never cared much about how others feel.
It's good that you are starting to care about others' feelings, and that you apologized to this person.  Sometimes absurdities of situations can make us laugh, but others think that we are laughing at them, and that can be very distressing, so we should try to control our reactions.
