Yep it is adapting to the environment. Maybe too much stress makes people change. I see that often in the office and could really bring out the bad side of you. I often do that too when I take public transport seeing people get on and off. It is very interesting especially around 4am in the morning.
Exactly!
4AM? wow! Is that when your day start or end?
Yes that's when my day starts. How I wish for a better schedule.
