When I said "What harm can it do"? I did not mean to confront anyone about anything. I simply meant the act of praying for someone is, at worst, harmless. Why one would feel obligated to mention it is what I don't understand. If you know the other person is a believer, fine; tell them you are praying for them. If they might be offended, do it but keep quiet. A word to the athiests; To look around you and witness the wonderful things we see every day, and say there is no God, is like getting up from a banquet and declaring, "There is no cook."
