Many things over the years. When I first got my high school horn out - and got asked to play at church a few times she said " If you are going to continue to embarrass yourself - why don't you take lessons?" I did.
For Christmas she asked what I wanted - ended up with a Conn 6B off Ebay.
She continues to put up with my playing - even though it is painful to her (others also I'm sure - but my wife was born with some defects in her skull and sinuses that cause higher sounds to ring with pain .. also can't do the roundy round rides at the park). So I try to practice when she is out.
