Made to feel like a bit of a twat

[HouseworkAvoider10]

My colleague is leaving his job, finishing tomorrow.
He does charity work, which involves sending stationery out to developing countries.
He has taken most of his stuff home and has also taken my whole tray of stationery to give to this charity abroad. It was on my desk yesterday.
I have been left with 4 small lead pencils and a black pen. Everything else is gone, including the actual stationery tray, my USB stick with stuff on it, all taken by him.
Its quite a lot of stuff, which I have collected over time.
Feel like a bit of a twat for asking for my stationery back when its going to charity, but these are the things I work with every day I will need them again.
He has admitted that he has it and says he will give it back tomorrow. He said its for the charity.
I do need my stuff back.
I think he's a CF.
AIBU?

That's so weird. I don't like people to even look at my favorite pens.

Find his car, smash a window, fill will baked beans. March him to the cash machine, tell him to stop being so miserable. Tell him it's for charity.

If his car has cloth seats, work with water and sprinkle the seats and carpets with cress seeds. Will be a sea of green by the afternoon.

He brought the stationery back yesterday morning. And he apologised.

Also what if the USB had protected or sensitive info on it?

Tbf if you are storing that kind of info on a usb stick left about in the office you probably deserve it imho.

Good to know he did the right thing in the end. Hope he seemed suitably contrite.

And of course she didn’t deserve it, it doesn’t matter if the USB was full of photos of OP naked except for a Santa hat, you never deserve someone else stealing your stuff.
