Sounds to me like you have the right stuff and are saying the right things, particularly as a father. Compliments to you and your son, Sir. Get your own horn and stick with it (Ambassador is a fine choice. Cheap, sturdy, dependable, and hard to outgrow...and as old as you are). It is a slow process when you are older, but well worth the investment. I started back after nearly 30 years at age 49 and, no kidding, sounded like a kazoo first time at it again. I like the different teacher idea. And, if I didn't have a family to feed and educate, I'd move back to Greensboro and beg Mr. Grier to teach me how to play right! Care to join me? Maybe he'd offer a group rate! Best wishes.
