Teenager:  Their attention is now growing out of the house rapidly. If called to their household duties, they can become so loud and obnoxious that it sometimes seems easier to just do the work for them than to keep educating them into responsible adults.

It would be good to resist this temptation, especially with boys: Now is the time where they should go through the training to be partners. If we ever want to have a society where women are no longer just cleaning ladies and cooks for their husband, then the teenager years would be the time to train the boys to handle their own clothes, do their own cooking, clean their own place and generally be a helpful family member!

Also they are now intelligent enough to do their first mental training courses. It will help them a lot in the upcoming years when they have their first sexual partners (and related competition battles), if they have a stable presence and clean emotional emanations!
