AIBU for traffic. Please solve this mystery for me.
Work in an office. Upstairs is another side of the business who sometimes come down to use my office. We don't often cross paths as work different hours. Not particularly friendly relationships between the two sides. There are only three of us in my office. Today I was alone.
Anyway, door into my office was totally normal yesterday. Today, sitting with a client, noticed that the door had a strange dark line on it from top to almost bottom. He got up to see what it was and said, ugh it's flies!
Got the hoover to deal with them thinking quite odd that they'd all died in a straight line formation, about 15 of them.
Went to hoover and realised not dry fly corpses but SQUASHED fly corpses with streaks of goo between each. They were stuck to the door with their own goo. (Hoovered what I could and got rest off with wipes.).
So, the mystery is - why? How did they get there? Why were they in a line? Why squashed? The door opened at its fullest doesn't touch the wall it's in. Nothing to squash them against!
There is a cleaner in the building who is odd but doesn't do our offices. We had our own but she's away. The only thing I can think of is someone from upstairs doing it because I mentioned to the boss that someone had left the lights and heater on in my office all night and two posters off the wall and on the floor. But I realise that is nuts. But the line of squashed flies is nuts!
