At 1:30 a.m. in Collegetown, you are likely doing one of three things: (1) buying a slice (or three) from CTP, (2) buying something shameful from the hot dog stand or (3) passed out on your bed with whatever regretful food item of choice beside you. At 1:30 a.m. in Barcelona, you are finishing up a round at a bar and getting ready to make moves to a club. You will not be passed out next to a regretful food purchase until 4, 5 or 6 in the morning.
