Not to take Donny's thread further South, BUT to continue the current thoughts, ...
Since day one of our marriage, I've told my wife "I'll bring the money in, you take care of sending it out" , otherwise we would have been broke !!! ... now, she does 'ask about' any music purchases I've made, but on the other hand she has never spent frivolously on herself - our kids and grandkids? well that's another story - ...
But she loves it whenever I am playing/practicing at home, even those times with all the repetition when I am trying to learn something new, or putting together my own backing track to a song ... sometimes when trying something new I will work on it with my headphones on and she will tell me I don't have to do that, she likes to listen ... So I've got that going for me ...
