Not quiet the same scenario but this reminds me of the many times people asked me for pens in school and never gave them back. It’s such a minor thing but it bothered me because I would often end up losing my favorite pens. Later I started carrying a bunch of old pens in case someone would ask for a pen during class.
If I might say, you should only say something if it’s something that truly bothers you. I would have laughed if I find my body wash missing from my bathroom after an encounter. However, should want to hide any valuables from now on.
