I'm a GUY.
-I've opened the door for many girls. What pisses me off is how many don't even have the common sense to say "thank you" so I have become rude now and just slam the door in their faces.
-I've helped a lady pick up her things after she fell....
-I've picked up someones card and ran after them to give it to them.
-I've stopped what i was doing to help somebody find their way when they were new and lost.
