My children are anyway. They've been trained that way.
Thursday is Steve's music night and has been for the last six years or so. He likes to get together with his music friends and jam. This was his band rehearsal night for back when he was in a band. Sometimes the guys went somewhere else (because you always go to the drummer. Drum kits aren't near as portable as a guitar.) Sometimes they came to our house.
This is why my kids are deep sleepers. The bassist always brings his amp, although he's been nice lately to bring his smaller one and not the one that's the size of a Shetland pony (the small one is about the same size as our dog.) Last night there was an electric guitarist in the mix. He's new to the group and according to Steve a very good guitar player. We also had a pianist and her husband (on the Seagull guitar) here for the first time. It was quite a crowd. It was also loud.
The kids fell asleep and stayed asleep.
This is what you call training. After six years of jam sessions in the living room, those kids can sleep through anything.
