I'm the only one in my family that sews/quilts. Some friends rely on me too. I won't go into everything I've done for others or how they expect you to be at their beck & call. If it was something they could do themselves, like sewing a button on, I started saying, "when you have time, I'll show you how to do that". When asked to make something that is going to take a long, long time, I say, "I'll get to it when I have time, but somebody else needs to learn how to sew." My favorite is - "sorry, that's something I wouldn't even do for myself". I don't charge people, so it's my right to value my time like they value theirs. I still help others, but most have learned I'll do things as I have time.
