I can muscle the jack up and town with the crank - blows the fuse right away if I try electric. It is a workout!
Yes, I allowed my son to move the truck while hitching - he asks every time - so all that happened is my responsibility in the end. That is why I am not asking my son to pay for anything. And, yes, you are for darn sure right that it could have been a lot worse - in fact, nobody got hurt, and that is all that really matters when all is said and done.
On the other hand, it is good to learn from our mistakes, and as my son spends time working on the trailer and replacing the tongue jack as well as cranking the tongue jack up and down the reality of actions and consequences will become real to him in a manner that my talking to him cannot convey.
Good judgment comes from experience; experience comes from poor judgment. At least, that is how I have learned the lessons I remember most!
