This is about polite and kindness.
People say treat others as you want to be treated, makes sense.
Others say treat others with courtesy and kindness because it is the right thing to do, but don’t expect them to return it because that is just looking for a reward and that is wrong.
So are both right?
I am confused I treat others nice because that is how I want to be treated, but is that wrong and just looking for a reward for me being courteous to them?
