Dear SJ,
My friend is being stalked.
I don’t know many details as he gets very tense and nervous talking about this, I can’t blame him. Firstly, he is a young adult and lives in a pretty rural area. He said this has been happening for months now. He is getting strange calls and a particular car is slowing down and looking at his house when it passes by. My friend knows a coder and somehow the coder was able to trace the number and the car together. Wait, it gets worse. He will leave his house and come back and the window in his bedroom is open. A lot of the time he will have a perfectly tidy room, come home and it is a mess. One time he cleaned the bathroom before he left to go somewhere, he came back home and the sink was dirty.
I should probably add that he lives with his younger sibling and parents. The parents work and the sibling goes to school. One time he came back home and saw that on the top of a stack of papers he had laying on his desk suddenly had a piece of paper with his girlfriends home address on top. Also, his curtains had a hole cut through them and his box cutter was missing. I’m very worried for him. What should my friend do? Has anyone had something similar happen to them? His parents won’t take him seriously.

Dear Concerned,
Okay, first of all, you and your friend have nothing to be worried about. There’s no stalker.
Everything you’ve described has a perfectly logical explanation. And, as we often do when thinking about weird events, we invoke the Fermi Principle*, that the simplest explanation is often the right one. Nobody’s sneaking around, watching this friend of yours and breaking into his room to write cryptic addresses on scrap paper, cut holes in curtains, open windows, and leave excess pimple waste in the sink.
Do you realize how ridiculous that sounds? Your friend is a nobody. He lives with parents and a younger sibling in a rural area. From the way you write, you’re probably both still under twenty, which means your friends about as worthy of stalking as some Holstein’s half-digested cud she’s burped back up and chewed on for the last half-hour. Why would anyone take any interest at all in this person, much less enough so that they would go to the trouble, for months at a time, to cruise the house? That’s not how stalkers do it.
We figure out an actually important person in our lives, maybe that principal who held us back in the tenth grade for no good reason (replacing the jelly in doughnuts with poo isn’t a good reason, in my opinion). Or that one girl who promised to keep writing while we were in prison and never did, and we follow them to plot our revenge. (We don’t actually do anything, remember. That would destroy the fantasy.) A stalker has to have some reason to avoid living their life like a sane person, and, frankly, from the sounds of it, your friend isn’t appealing enough to bridge that gap.
So what’s happening? Again, very simple: Your friend is making this all up.
