Just the other day I gave a homeless man the finger when he asked me for a change.
That seems disrespectful. Why would you do that to a homeless man?
He was dressed well he obviously didn't need the money.
That was a rude thing to do to that man. You shouldn't offend those people who are homeless since they have enough to worry about as it is. You should be more kind and considerate since you don't know what they are going through.
I don't care, I think what I did was funny!
Homeless people are vulnerable population and it's up to us to look out for them. Their lives are already difficult, so don't go around offending them or you're going to look like a bad person.
