So earlier on today I opened the front door to go outside. While it was open an annoying buzzy fly flew in. I came back in later and the fly was being really audible flying about the place. I thought "I can't move well enough to kill it, shall I ask for help?" Then I thought "Nah" and just went and sat in my doorway with the door open. After 3 or 4 minutes I thought "Nah, he's still indoors" and reached out to close the door and give up. And the fly then flew over me and back outside.
