Input: Text: literally riding on the bus as i type this.  

i came out of the library and walked towards the bus stop to catch the bus to go to the parking lot where my car is.  i'm a commuter. i look at the app that estimates when the bus is going to be at the stop i'm at and it says nine minutes. i'm pretty bummed out because it's chilly and i don't have a jacket lol but then i see my bus already there and i think this is my lucky day.  the bus door is open so i run towards it and stick my arm in to alert the bus driver i'm trying to get on.  cue the bus driver closing the bus door on my arm.  my entire arm was in the bus while my body was not.  shit hurt like a bitch.
