This boyfriend — named Nick — who went into the attic of his girlfriend's apartment and found his name carved into the wall with a pentagram underneath:
"Found this in my girlfriend's loft. She only moved in three months ago and says she has never been up there. Guess what my name is..."
While most of these are super creepy (thanks for posting this in the morning not at night) this one is easy. Micro etching on the glass will cause bubbles to form in the same pattern as the etch, either advertising or prank...
Cool story bro
