Since the subject of lending labor came up, I might as well toss this out there. Many years ago I had a truck with plow, and after doing my yard I would go over to my moms and do her yard. The woman that lived next door is a an older widow, with mostly no-show kids. Felt sorry for her when the snow started really building up in her yard one year, so the next time I was at moms I figured I would do her driveway. Long story short, forgot I had the hitch on the back, slid a bit in close quarters and dented her garage door. Showed it to her and pushed out the dent. She said don't worry about it, the door is old and one more dent wont matter. That spring one of the no show kids hands me an estimate for $500 to replace the door panel! Well, they got a new panel off me but I learned my lesson. The following winter I went over to moms to plow after a deep snowfall and plowed her yard. Than went in the house and got a hot cup of coffee, & went back outside and watched the no-shows shoveling after telling them I did not want them throwing the snow onto moms lawn. Now THATS Karma!
