One odd thing that I remember that happened shortly after we purchased and moved into that house I mentioned: We were about to sit down to supper, when we were swarmed with these bugs. There were no open windows or doors, and yet within minutes the entire dining room was filled with them. We grabbed some fly swatters and started smashing them but always there were more. I felt that it was a bad omen, or a sign of unhealthy energy in that house. The really weird part was after that one time, in the three years we occupied that house, it never happened again. BTW, we learned that the bugs were called Asian cockroaches.
