Needless to say, I was perplexed. He seems like such a sensible boy. Why would he do something so dumb? Anyway, he went to school and had a very hard time staying awake in his classes, and hopefully that taught him his lesson.
But seriously, why do they act that way? There have been studies done recently on the teenage brain that offer some answers. They have found that teenagers' cerebral cortex, the front part of the brain that helps with judgement doesn't start its huge development until age 16. (One reason why it's good to make teens wait to date until 16). Also they don't have the experience to make good judgements yet, so sometimes they do really dumb stuff.
So if this happens to you, and it will...it's a good idea to remember the above and teach instead of criticizing. Help them learn from their experiences by talking about it with them often. It will preserve the relationship much better if we are patient with our teens as they learn.
There is a book that explains why teens have these problems called, "Why do they Act that Way?" by Dr. David Walsh, PhD, which can really help you understand teens better and have more patience with them. It has helped me to be more understanding when my teens have made some really dumb decisions.
