That's crazy. Did you ever figure out who it was. Get it "resolved"
I thought it was the 60 year old lady across the street who used to work for Ford (now she works for a auto supplier)....she even told me for the first time meeting her in the summer, to my face while wearing a VW shirt, that she "hates VW" and I thought I had it pinned on her.
BUT then she followed it up that VW just sucks to deal with, from a supplier stand point.
She swore up & down it wasn't her after I showed the note to her.
Then I thought it was her neighbor, a Mustang owner. He's middle aged & always revs his V6 Mustang (with racing stripes!) and speeds down the street whenever I'm outside. Super weird/annoying.
I later found out that it was 99% most likely the old guy two doors down from her though, a retired Ford employee that is one of "those guys" always writing to the city newspaper and complaining. A keyboard warrior
He's the dumbass with the brightest porch light on his house kind of guy too....lights up the whole street, very annoying.
I let it go after that and just laughed it off though...I'm not changing anything I do
