Someone left a hand-written post-it on my front door (single-family home in Minneapolis) saying, "Sorry I missed you, please call" and signed, "Yer. I've never known anyone named "Yer" so I'm guessing they're a sales person. Contractor & house flippers often leave flyers and notes on my door and in my mail, trying to sell a service or buy my house. Not having a clue who "Yer" is, I did not call the number on the note.
