Thank you gift from a boy in faith formation

Thursday night after I got home from campus, I came down with the worst stomach bug I've had in years. Ugh! The details are TMI, but let's say you can just rip yesterday's calendar page out. At this point, I am up to ginger ale and toast (one piece). Since I don't eat bread or drink soda, this took some doing!

The case of the missing chair: recently I moved into a new (much nicer) office. The prior occupant left behind a wooden side chair with tattered upholstery. The chairs in her new office are in better shape, and she said I could have it, or if I felt it was too forlorn, I should throw it away.

I liked the chair, despite the worn fabric, and decided I would keep it. When Bob visited to see my new space, he immediately said "that's a Gunlock chair." So I bought fabric, and hauled his cordless screwdriver to campus on Tuesday to begin the reupholster job.

I took off the back, but discovered the seat required a regular screwdriver, which wasn't in the case. I decided the fabric needed ironing anyway, so I'd have to finish on Thursday. Thursday morning I arrived with another screwdriver and an iron...and my chair was gone!

After looking around the department (lots of moves, painting, etc. taking place at present), I contacted the office that has responsibility for such tasks, and was referred to email elsewhere, which I did. No response. Suddenly our department coordinator had a bright idea...she found my chair in the tunnel (four stories below).

Now, I have some ideas...but who took my chair and why?

Studying social class in Toleration class. I assigned groups of students a class, and had them make posters.
