A typical teenager. Dad doesn't know a thing LOL. Thats why I always tell/told mine they should get out of the house now while they still know everything LOL

Seriously, we want our kids to be proficient. We want their skills sharp and to kill quickly and humanely, but each kid is different and most react/listen to those outside the immediate family more than they do to the ones closest to them.

Shooting for a set amount of time can fatigue them, causing them to make poor shots thus leading to frustration for both parties involved, ie, son and dad.

An idea for you and maybe it's been mentioned, I did not read thru all the posts, but start taking him to some 3-D shoots. Let him challenge himself by seeing how good the others are, and letting him save face by seeing where HE needs to make improvements.

Besides, both of you will have a good time. Making a game out of it will be more productive than a classroom session and he'll probably end up meeting some kids his age that he can relate to and heed the advice THEY give him.
