Have you been flirting with a teacher or librarian lately? Maybe it's their calling card and they don't want you to forget about them. That's all that really comes to mind, haha. Is there a return address? was it addressed to you with a printed label or did they hand-write your name and address?
No, no, we have to explore @Ericj32 's theory because I absolutely love it. Have you been to a library lately? Any encounters at a PTA meeting? I'm already imagining a quirky meet-cute.
I would be concerned that Mather has your address, haha. In all seriousness, though, please keep us posted in case another pencil finds it way to you. I kind of need to know how this ends now haha. Maybe it's like a secret santa thing?
@RenegadeMonster if someone sent me just matches in the mail I would be making sure that my home insurance is very generous in a house fire situation (and also living in a hotel for the next few weeks).
If it doesn't have your name it could be a mail scam. I sell someone a ps5 in your city. I mail a pencil to a random address in the zip, provide the tracking number. Or says some person on reddit.
