This office does not know how to take "NO" for an answer. One courtesy call to remind about the cleaning being due is quite enough. A second call the next night was OK. The third night when you called, it was annoying. The fourth night you called, I asked you not to call back. The fifth night you called was an unnecessary interruption in my work, and the sixth night you called was bordering on harassment. I politely asked you not to call again on the fourth night. Why you continued to call, I can only guess you intentionally wanted to aggravate me. If you call again, I'm calling Dr. Lawson personally.
