Piano teacher is going to get me in trouble

First she tells me I need to get my youngest singing lessons… as that will help with his piano. Just last week, she told me (with him standing there) that he should learn guitar. D’oh. He has been asking for a year to learn guitar. Since he realized the drum teacher my oldest goes to is a guitar player as well. Right now, the teacher has guitars and some small pieces of equipment here and there, but I wonder if he ever considered superb orange cabinet from guitar center. You certainly wouldn’t miss seeing it! Ahhhh… music.
