different people
Every 30 minutes you meet a different set of people. At 7:50 the bus will greet all those determined to be early to their 8:30 AM lecture. At 8:05 you’ll meet the ones who probably woke up early enough to make the 7:50 but took their time getting ready and organized before leaving the house. At 8:20 you’ll meet all those trying to squeeze into their class without being late. Hoping the bus catches a red light to blame their self inflicted dilemma on something else. At 8:30 the cycle starts all over again. I typically aim for the time frame around 8:30 because the crowd is the lowest and most live in their heads.
I personally am always early to class- like sit in the academic building at least an hour before the lecture begins type early. Sometimes I do homework and sometimes I pretend I’m doing anything productive over just observing the interactions happening all around me. I sit at places for so long that I see people meet, fall in love, live their life, and pass away. But all during different hours of the day, of course.
