Let me start by describing my building, broadly. The floor plan of my building is like a big H shape. The horizontal line in the middle of the H is the hallway. Each floor has five apartments, one shooting off on each prong of the H's vertical legs, plus one small one in the middle of the horizontal line. The elevator shaft and stairwell face the small apartment. Anyhow, my apartment, like the other big ones, is long and narrow. We're on the bottom-left prong of the H, for reference. We have windows on both sides. On the north side the windows face into the hole at the bottom of the H, on the south side they face the apperture between the buildings on our street and the backs of the buildings on 112th St.
So this is all to say: No matter where you go in my apartment, there's a window facing out on a wall of more windows. Half the rooms face toward the backs of the 112th St. apartments, the other half face the the apartments on the bottom-right prong of the H.
Let me re-emphasize a point: Every room here has a window. Every room. That includes, but is not limited to, the bathroom, which has a nice big window placed conveniently right over the bathtub/shower. The glass is fogged, but when the weather gets hot in the summer you've a choice between being muggy and hot in the bathroom or allowing airflow at the cost of your shame.
Lately I've noticed that at least one of the girls who lives in the apartment on the bottom-right of the H one floor up likes to take showers at night. With the window open. The window opening directly on the shower that looks straight down into my kitchen.
This puts me in a bit of a spot. I like to use my kitchen. At the same time, I don't want her to glance out the window and see me there staring, looking as though I've staked out a watchpost to oggle.
I blame whoever designed the building, or at least whoever did the interior layout. Why would you put huge windows right over the long end of a bath in an apartment facing a wall of other apartments? Especially, as in the case of my shower, where, given a choice between a half of the wall hanging over nothing and a half hanging over the shower, they elected to put the window over the shower (or the shower under the window, whatever).
I suppose, though, the whole thing is another incentive to get in shape for the summer.
I could think of worse problems to have...
When Keri lived on her own, the bathroom in her apartment had a window in the shower. She had horizontal blinds over the window so that she could allow air to vent through but use the blind angles to prevent viewing from the driveway.
However, your problem is that there are people above, below, and at level with you, so those won't work. *shrug* Grin and bare it (pun intended...)
