Bumper sticker on my truck: "Yes this is my truck. No, I won't help you move."
Went to help a friend move and was just supposed to load the truck. Everything was supposed to be ready to go. When I arrived, they were Juuuuuuuuust starting to pack boxes. Nothing was even close to ready to go. I helped load a couple things on the U-haul and then left. I don't have time to be used. Needless to say, those friends have been summarily replaced!
Movers is the way to go. Best $400 you'll ever spend. They usually won't damage your stuff 'cause they have the right equipment which you probably don't have or have to pay extra to get.
But nope, I don't help friends move or paint. And they're still my friends. Mostly!
