Alan (below) understands a basic principal of living in a village.
I live where many of my fellow skill trades persons have grown up and still live and work here. A contract is seldom written between us; an hour of hard labor to one other is returned when their need is great as a gift. Keys to places are left under rocks and tools are borrowed. My heating contractor's son currently has metal in his eye and he has six other trades persons offering FREE LABOR to lug boilers into a basement or to install piping for a day or two on the next boiler job. He is 60+, has gout, a bad knee, and the backup (retired) helper is in FL for 6 weeks.
If work needs to be done, a price is agreed. Deposits are paid, work is done to where pride is seen, and payment is paid as arranged. There is no such thing as back-charging or whining about it is too much.
I am equal in the group without regard to age or sex or physical size or wealth. The older folk are listened to and valued for their expereince. Many still work fulltime into their 80s.
I think I live a good way and my life has mostly fun moments and pleasant work days. I have chosen this style of living. I sleep well and I have friends who I can count on without an expectation of every encounter has a hundred dollar bill attached.
I think we here all live better for it.
