If i saw the guy working on the tree, i'd just pull in and talk to him a little, then, suggest he get his tree cut up, and you'll help him, your bored and need to burn off some energy, do it all at his pace. I'm like a lot of these other guys, i don't mind helping people, i've stacked more firewood than you can imagine just ''helping'' some one. One day went i was working on a road with some other guys, a guy showed up, opened up his gate in the field pulled his pickup inside the gate and started loading firewood. I sat there for about 2 min feeling guilty watching him. Got out of my truck, started loading wood with him. He stopped loading the wood and said, ''what are you doing'' i said to him, Gene i can't sit in that truck and watch you load that wood, i'm just not that kind of a guy. We got his pickup all loaded up and he thanked me about 4 or 5 times. I love doing that, just helping people, no reason, i just like to do it. I can't sit and watch people work. And, i don't expect anything for it,no favors, nothing, its just fun for me.
