It is rare that our house is actually quiet when I'm home. (Well, super rare, I guess: our fridge is pretty noisy.) But even if you discount that, it's very rare that I have much in the way of alone time when nothing else is going on.
Living in such a small apartment with 3 other people -- even people who are relatively self-supporting -- just leaves so little psychic space for anything else.
I dream of an office for myself; a small studio for photography and video; a sunroom of some kind; I dream of large bathrooms, I dream of high ceilings.
It's not what I get, but maybe someday.
Until then, I just sometimes sit back and just enjoy the quiet times. Like now.
