Often I'm following someone into a building and entering the same door, and most of the times, the person in front won't even try to keep the door open so that it wont close in my face. I never do that. Knowing that someone is right behind me, I'll even wait a second or two and hold the door open for that person. I guess it has to do with being well educated
How about if you're in a bus and someone older, or a female, has to stand up, while you're sitting down. Will you get up and offer your place to them.
I know some people who were nice to others and it turned against them, and the person standing said, no thanks you don't have to get up for me. I can stand up, I'm not invalid you know...sometimes, making you look stupid for even asking.
