No, not at all. I do things for others because it feels like the right thing to do not because I am building up a 'store' to use against them later. Now, if you'd asked if I feel used when people ask a lot of me and never give me anything in return the answer would be yes. I see this as a two-way street where if you constantly ask me to do something and I always do it for you, I'd hope that the person would reciprocate if I needed something done but I don't 'expect' it. What bugs me about this situation is how people have learned that I don't like saying no and they use that against me by guilting me into doing things for them.
