Relax, it's just chaos.
We often discuss this topic with my family when we eat together. We have NO IDEA what they're doing. Some of them are litterally doing NOTHING. It's really a weird phenomenon.
I just asked my grandpa if he ever noticed this, and he said he's noticed it as far back as the 50s. Just sitting there like mannequins doing nothing for a really long period of time.
