Auto Tech 101

So I come out of the house only to see my son with the hood to my car popped up. I should have treated this situation like that of a suspicious person in a restricted area of an airplane but no. I entertained all his questions of "What’s this" and "What does this do" He became especially interested in the battery and how to clean the terminals. Knowing he was taking Auto Tech 101, I thought this was a legitimate question. He removed the terminal cables and proceeded to clean connectors and terminals. 5 min later he was done and the hood is down. “You are good to go sir.” Great, because I had an errand to run. I was merrily heading to my destination when I reached the main artery where I needed to turn on to. It’s a 4 lane road with high speed traffic. I looked to my left and see only a semi but plenty of time to pull in front of. I do so or at least start/commit to my turn. But then there is literally no power. I pump the accelerator but realize all lights are off. At this point I sense I need to accelerate or be a grill decoration of the semi that is bearing down on me. Luck was with me as I had enough adrenalin to turn a powerless steering wheel to the edge of the road. This was quickly followed by an irritated blast from the Semi's horn as he missed me by inches. As I am standing there under the hood thinking WTF, it dawns on me what had transpired 30min earlier. I checked the cables and sure enough they pull off easily. Apparently next week in Auto Tech 101, they were going to cover tightening bolts that you loosen. Being a mile from home, I call home but no answer, son has now fled the crime scene. A quick walk home and back earns me a socket and wrench that don't fit each other. Socket work good enough to tighten it so I can drive about 200 feet before I have to jiggle the cable, drive 200feet jiggle cable, drive..... When son finally gets home I ask “what about tightening the bolts back.” Response "Oh". Sigh
