Mr. Chamberlain you asked the question " how did I hear the drawer open while in the shower?" If you have a cabinet of some sort against a wall that is close to a wall where you are and and when someone pulls that drawer open fast and it slams on the stops, it makes a loud noise. That's the only way I can explain it to anyone. Hard to believe I'm sure but I have no reason to make this stuff up. I know I shouldn't take offense to anything said on here, I was just and still in shock about this. I appreciate all advice honestly.
