Riding elevators is so weird. It’s all, “Hey, how about I get into this small metal box with all these strangers and then don’t say anything to them and instead sort of nonchalantly stare at the floor numbers?” If you were asked to get into any other small box with strangers, I would imagine it would be quite alarming, and that you would also probably say something to the people around you, like, “Since we’re in this small box so close to each other, allow me to introduce myself.”
Also, the building that my internship is in actually has no 13th floor. I always thought it was just a myth that there were buildings like that.
