I have this really polite guy friend. If we are ever shopping together and I'm carring a bag of mine and he offers to carry it should I let him carry it or say no thanks?
Why do I get the feeling that there is more to this question than what you put before us? What could possibly be wrong with someone helping you carry a bag that is too heavy? Let the guy help you unless he will be expecting sexual favors or something. I love the idea of a guy with manners.
