There are still a lot of flies in my flat. My trusty fly trap has not wiped them out. They seem to like my bathroom as well. I did wonder why they liked the bathroom, but I now think they are feeding of my shit. This is so nasty, that I have taken to putting the lid down on the toilet.
I have noticed that some women get very upset if the lid of the toilet seat is not kept down. Although in my case there sometimes seems to be an issue with "missing". I have always wondered why women worry so much about the position of toilet seats. I have never asked for the reason, but made some crude guess made on biology. Now perhaps I have found a reason.
