You could, also, remember that it could always be worse. I have one coworker who clips her toenails and fingernails in her office. You can hear the snip, snip, snip. Another coworker, who is 4 years younger than me, acts like he's the president of the company and knows everything. Another coworker makes personal calls all day long but will be the first to tattle if someone else is doing something non-work related.
If all you have to put up with is a little humming count yourself lucky.

We must have different Gods. My God said "do to others what you would have them do to you". Your God seems to have said "My Way or the Highway".
