Peace of mind" is underrated. I passed on a supervisor role to weld.

So you're saying small groups should hide their methods to stay safe?

Question if it's really that serious though. A stuck pixel is a pretty easy thing to check if you just cover part of the screen with your hand first. Hard to really waste 4 hours unless you're trying to prove it's aliens real bad.

4 years ago I caught my ex doing the exact same thing at a Chili's in Dallas. Watching a specific friend's stories twice while we were sitting together is not a boredom move, it's a curiosity move. You were not overreacting at all. That kind of behavior usually means there's still some kind of interest or unfinished business there. Did he ever act weird around that friend before or after that dinner?
