Stupid teenage tricks

I know that the teenage brain is missing in action, but I wasn't sure just how much so till today. Big Brother (age 14.5) mows the lawn. I asked him to do that today and then put the tractor back. He mentioned that he thought tractors should be able to go on the road. I told him that he was not to take the lawn tractor on the road. He mows the lawn then everything gets quiet. I thought he had put the tractor back in the shed. No such luck. He decided that taking the tractor up the street was a good idea. No...I have no idea why he would think this was a good idea, but he did. So I took off in the van after him and found him pushing the tractor about an 1/8th of a mile from the house. It had died while crossing a neighbor's driveway. Not only had he taken it out of the yard, but he didn't check the amount of gas in it. He moved the mower out of the way and I brought him back to get the gas can. He refilled the mower and then drove it back home and put it away. He is rightfully embarrassed and I don't think he will do it again. I am going to be completely grey before I am 45 (and I turn 43 this year).
