As I walked into the room with my new attractive
boyfreind, whom I spent most of my time with nowdays, I could help but feel "mean-mugged" by my ex-boyfreind, Brooks, who was drowning his
sorrows in alcohol at the end of the bar, becuase he was recently fired from his job, and has resorted to selling cheap
elevators in Boston.
