Dear person on the fifth floor eating who knows what and making an insane amount of noise while doing so,
Do you know that you are on one of the quiet floors of this library? I am one floor below you and can still hear you as if you were sitting right next to me. If you would like to make so much noise, please go down to the first or second floors. Some of us are trying to study... I think the guys at the table across from me would agree. I mean, it is Friday after all and you are making it even harder to be at the library.
Sincerely,
I'm taking 18 credits, working two jobs and trying to study for three tests....
