I hear you.

Hey neighbor,

I don't know what your name is and I couldn't care less.

You need to know that our walls are paper-thin.

As much as I hate to eavesdrop, I can't stop from hearing your voice.

Oh, and you know how your balcony's beside my window?

You need to stop giving me carcinogenic materials.

I can't open the windows because you always come out to have a smoke.

If you want cancer, do it at the comfort of your house, not your balcony.

And please, if you can, stop yelling.
