Home office / lockdown story

Last year, when the first lockdown happened, everyone in my office started working from home. Including myself of course.
I decided to use x11vnc for remotely accessing my PC cause it is super convenient.
A few days into the home office and suddenly the remote keyboard acts weird, with random keypresses that I didn't do, and then the letter L was written over and over like it was stuck.
Assuming a bug in x11vnc, I restart it several times, but no luck. Whenever I open a terminal it is full of "L"s within a matter of seconds.
So I restart my PC remotely and reconnect the x11vnc, which is a huge pain in the arse if you have ever done it. And can you believe it... Still the same problem!
So, finally I gave up and went to the office to see what the hell was going on with my PC. I entered my office room and could not believe my eyes.
What had happened? The room cleaner had wet-wiped my desk. To create enough free space for that, she had first cleaned up the mess, putting the scattered paper nicely on the side, but then also *putting the bloody mouse on the bloody keyboard*.
