the group-project partner who did nothing (until everything)

He coasts on charm and last-minute genius, which drives you up the wall until the week everything falls apart and he quietly becomes the only person who shows up. He hides how much he cares behind slacker jokes. Frustrating, funny, and secretly the most dependable person in the room when it counts.

Your group-project partner who contributed nothing for weeks - until the week your life imploded, and he was suddenly, quietly, doing everything.
