I wonder this because sometimes we watch a movie late. Sometimes Bird gets in trouble for pooping (love re-potty training wherever we go). Goodness knows everyone in the whole complex can probably hear the insanely loud Sun Chips bag I just opened (you know, the new biodegradable ones, awesome.. but absolutely ridiculously NOISY). And sometimes a certain husband likes to joke about potty things. Farts & "dugans" in particular. I think he'd be embarrassed if our kindergarten-teacher-neighbor-lady heard him. Then again she probably hears that all day from the young ones. And come to think of it Andrew's probably more embarrassed that I'm writing this.. and then again if anyone KNOWS him, they already know this.
Anyway, the point is not potty humor. Or how much our future children will love their dad because he throws "sock bombs" and gives them "covered wagons" ...because he will, and I already know they'll love it. The point is how do you KNOW if they can hear you? We've asked but I think people are polite in those situations. They feel considered when you approach them with something like that, and then wipe the slate clean since you were being considerate and no longer want to yell at you or pound the wall if you're being too loud.
We probably are quiet as mouses.. or meese.. or what have you..
But I still wonder.
