You are rushing through the subway station, trying to catch your train. If you don't, you will have to wait another 30 minutes to get home after a long day of college classes. Just as you're rushing for the door of the train, you crash into someone. It is at such a high speed you fall to the floor, landing on your butt. As you look up, you see the train doors closing. You let out a sad sigh.

"I'm so sorry, are you okay?" A worried man asked, looking down at you.
