I’m so sorry I missed our appointment for this morning; I got held up in a faculty meeting and could not break away.
Please call me to reschedule. I am available any weekday except Friday from 2 to 4 P.M., and because I missed our meeting I also am willing to drop by the office any time Saturday if that works better for you.
I have just moved into Apartment 32B, and am enjoying my stay here. However, I do have a concern about one of my neighbors.
When I signed my lease it was emphasized to me that there could be no more than two persons living full-time in a studio apartment. That is definitely not the case in the apartment directly above mine, 33B.
During the one month I have been here, there must have been at least six adults and three young children somehow squeezed into that studio apartment at any one time. The constant noise, the traffic into and out of the apartment, and the four cars they use is very annoying.
Please look into the matter and advise me of the resolution as soon as possible.
