Mine is cross between Damien and faulken's stories.
Round about 6th or 7th grade, they brought a company in for a presentation to the students. Instruments and lessons as a sales pitch (we didn't have a band program, music was nuns, tambourines and those toxic black recorders that tasted like a radiator hose). I was one of the kids that caught on quickly to how to buzz my lips.
Mom wasn't having any of it. "You'll take piano lessons. Nobody ever takes their trumpet out to play for company."
Moms...HUH! Good God! What are they good for ? Absolutely nothin'.
My older brother came home from high school the following year, after a drum corps had made a recruiting presentation there. And came home with a baritone bugle. Shiny chrome. Schwing !
I ended up on a valve-rotor soprano and mellophone, then 2 piston. I've taken up the trumpet hobby Lo! these many years hence. A major regret in my life is ever letting it drop, but work and life will do that to you.
I still get a burst of cognitive dissonance every time I have to mash valve 3 - Like a button in a 747 cockpit, I'm not quite sure what it really does and I'm afraid to press it.
