My mouse is gaslighting me.
It's a wired/wireless combo mouse. If I use it wirelessly, it'll occasionally skip due to interference, as all wireless mouse do. If I plug it in, it sometimes (like, once every 3-4 days) spontaneously unplugs itself. It does this while I'm actively using it, which is annoying for obvious reasons. I installed an app that notifies me whenever any USB devices are connected or disconnected, so I now know that sometimes it unplugs itself in the middle of the night too.
