How to chase flies away

Hey! Have you encountered flies entering your room and then flying around right in the middle of your room? I find that it is quite annoying. You too? Well, then this is truly an absolutely great trick to know. It is actually quite simple to chase them absolutely peaceably out of your room: all you need is to have one of those bigger ceiling fans. Since this fan is usually located in the middle of your room, and since it generates an air current, the flies won’t like and they simply fly away. I observed even that they usually fly away through the windows. That actually proves that flies are smart enough to know where the window is! Contrary to popular believe!
