Am I wrong?

Not to me it isn't. Personal choice.

Once in a while I will volunteer to help someone but it's when I can get to it.

I know exactly what you mean. I did tell them that I wanted to load it onto my trailer and bring it here, that I would look at it when I could. Somehow that got twisted into they would run it down and help me with it. I never got the feeling they do not trust me wit it, they just want me to look at it right now.
They called and invited us to dinner tonight....and reminded me to bring my meter. With it being the 4th we declined.....my dogs freak out over the fireworks & we do our best to see that they are not alone on the 4th.

I don't know if anyone would accuse you of being wrong for feeling like this, but maybe it's a little worrisome. You know, by sort of "withdrawing", if that's what it is......I've got a whole story on this, but I'm not going to get into it. I live out in the desert, remember?

If it's just you not wanting to feel committed to working on other people's stuff, I know exactly what that feels like. I started just telling people "I'm feelin' lazy", then laugh. Works every time. OR.....I'll tell them "you bring it over, you do the work, and I'll direct" It gets old when people want you to do them a favor and get their stuff running so they can flip it. LOL

I understand the worrisome point. Not withdrawn, at least I do not think so. I have been over there place numerous times for dinner and to play Canasta. Have went to dinner with them a few times. I do want to help them....but on my schedule. I had every intention of going over on Saturday but they will be at a neighbors for a graduation party. I offered to bring the thing here but that went over like a lead balloon.....
