I've also learned another interesting fact about the family who lives above us. They are extremely clean. Their bathroom is located directly above ours (all units resemble each other in apartment buildings), which is located directly behind the livingroom wall. So as I sit in my livingroom, I hear the water from the shower upstairs running through the pipes. ALL DAY LONG. They shower in the morning. They shower in the afternoon. They shower at Midnight. These people shower more often than anyone I've ever met.
I thought by now I'd be used to the sound of water trickling through the walls of my livingroom, but I'm not. I don't think I'll ever be. Even Joey notices it. The water starts going and Joey goes to wall saying, "What's that, Mommy?" And I can't use the word 'shower' to explain it to him, (remember this?) So I usually just say, "Oh, that's just the water in the wall honey." Again.
