Totally get that feeling. Sometimes finding a quiet spot and just watching people is a nice break. I've killed time with a coffee doing the same thing.
Used to think people-watching was kinda boring. Changed my mind after spending an hour at a park bench last week. Watched a kid learn to ride a bike and a couple having a picnic. Felt really peaceful and gave my brain a quiet reset.
Honestly that sounds like my personal nightmare. Sitting still that long makes me antsy, and watching random people just feels weird. Always got my guard up in public spaces anyway, it's not a chill vibe for me. Give me a loud job site over a park bench any day. Nope, not my idea of a reset at all.
