someone make it stop...please

This is really starting to get on my nerves. All day long, the toilet has been making this weird hissing sound about every 10 minutes.

Now, this is not really an unusual sound when you live in a high rise. I think it has something to do with the intricisies of a thirty-story plumbing system. My guess is that it relieves the pressure or something like that. Normally, it happens a couple of times a day, and is barely noticeable.

At first I thought perhaps someone is home upstairs who usually isn't, and perhaps this is because he or she is not feeling well. That could explain things. But every ten minutes -- come on.

There it goes again. Ugh!

I guess I will have to talk to someone in the morning.
