Sitting quietly in a room for hours at a time literally doing nothing. I once got curious and just sat in my living room for around 10h straight because I wanted to see what my living room and neighborhood was like at night. Im talking no phone, TV, or anything else just me sitting alone staring off chilling.

Fun fact: I average 3 cars an hour over night in my neighborhood and we aren't really a busy neighborhood off a couple side streets too. Some of the cars leave then come back a few minutes later. Probably drug dealers or something.
