It's always a bit of a shock to step back outside after spending a few hours in those windowless buildings, especially if you went in during the afternoon and come out late at night. The change in temperature and the sudden silence of the streets compared to the constant ringing and chatter inside can be really disorienting for a minute. I usually find a quiet spot to just sit for a second and let my eyes adjust to the natural lighting again before I even think about heading home or finding a place to grab some food.
