Weird? My wife is exactly the opposite. She won't let me accept favors when they are offered, but she sure is liberal with offering me up to do favors for others.
When people loan you out, it is an eye-opener.
I'm not bad with a carburetor. Relatives think that a device that won't run must have a bad carburetor, and that does not discourage them because they know right where to take it. Once my 90 year old uncle said something was wrong with his tractor, and my brother coughed me up to run over and fix the carburetor. And if it is not the carb, no matter, since surely I can fix anything (according to them.)
I got a call "Uncle RC wants you to come by and fix his carburetor."
"How does he know it is the carb, and how does he know I can fix them?"
"I told him you are a wizard at carburetors, and that you'd fix it."
"Were I a real wizard, your head and your butt would be switched from now on, but unfortunately, all I can do is make your carb. repair man disappear...poof!"
I went over and fixed the thing, he was not long for this world, and it became a duty at that point, though I feared he was not actually safe to drive it.
The only carbs. I've done since that day are on my ST1100 and on a buddy's generator---we drop what we are doing to help the other all the time, it is our deal.
My dad an I parted company (on good terms) because he was loaning me out to the neighbors (for free) to spray all of there corn and gardens. I was flat busted broke, but needed money for college as I was on summer break. One day, I reminded him "you always said there is not much a poor person can afford to do for people of means free of charge. I'm in college, so how do you loan my out to others to take care of their crops?"
"When you are under my roof, you will do as I say."
"Well, I understand that, but I need you to say different."
"They are my friends, and you will help them."
"I won't help them any longer, Dad, not for free. If you are paid, or I am paid, that's one thing."
"Then you have to leave."
"I understand, and I will pack up and leave right after work."
"I don't want you to go, but I need you to do what I say."
"I don't want to go, but I need you say different than 'go take care of all the neighbor's crops for free.' I am in college, and I need every penny, and I'll still risk miss-meal colic regardless."
That was the impasse, and I left that day, but visited him the next, and every couple of days for a while to make sure that what happened is what was remembered, and no alternative theories crept in, and to be sure he didn't get lonely. And I would help him some, just not all the neighbors.
(The above are not direct quotes, but pretty darn close, I wager.)
