I have raised 5 sons and am finally on my last 19 year old

I worked very hard with the idea that they should at least know how to cook simple stuff and then clean up their own mess (apparently this doesn't include counters

). Now the last one wants to be a chef

. Now I thought gee I finally got through to at least one of them. So he is now working in a fairly good restaurant and loves the job. The only thing that gets me is when he is home he will ask the same questions about cooking as the others did and leaves the same mess

. He doesn't seem to know about cleaning as you go or at least do it after and will put food in the micro wave without a plate YUK. Apparently I didn't tell him to put it on a plate. I have come to the conclusion it is a faze that lasts until they get married and their wives take over where we left off
