Overview
Relying on other people to help you out once in a while is not the same as using people to your advantage, so don't sweat it if someone accuses you of being a user today. You know the real story, and that's all that matters. But if it makes you feel better, reach out to your accuser and ask them if you can do something for them. Showing them that you heard what they had to say and showing them that they are wrong will strengthen your reputation and your relationship with this person.
