people on the subway that be doing hella gross things. picking they noses and coughing all over everyone. that stuff gets on my nerves!
Dude, seriously. This. +1000. One time a drunk guy on the seven train stood with the door between two subway cars open and pissed out of it. Now, the 7 train is ABOVE GROUND thus he may very well have pissed on a bunch of unsuspecting pedestrians below.
