At times it feels like all I do some months is spend my weekends moving people. 1) I have a truck. 2) I know how to load a truck fairly efficently. 3) My PawPaw 'kept' one of those nice sets of u-haul handtrucks back in the 70s and they still work great for moving appliances (his actions are not condoned, but do come in handy occasionally).
I don't mind helping people move. I get to see their things! I'm fairly nosey and like seeing my friends things. I remember one time a buddy's wife was thanking me for all the trouble I went through helping them move time after time, and I replied, "that's okay, I always learn something everytime," as I handed her her underwear drawer.

I do occasionally try to convince my friends to part with things as they move. Almost picked up a motorcycle cheap that way, but then his brother showed up...dang it! That is how I got my first tent, which only needed a little duct tape and it was ready to camp for several more years.
