TrainRoomie: " I wish I had known. I just went train on the ice cream. I'm not at all hungry. Look at this food baby."
Roommate: "That's okay. I'll just go pick something up then."
TrainRoomie: "Will you pick up some more Ben & Jerry's while you are out? I promise not to go train on it this time."
Roommate: "I'll buy a lot. Tomorrow we can go train together."
