Everyone grieves in his or her own way.
On Girls Season 3 Episode 4, Hannah loses someone in her life and everyone around her is surprised at her reaction.
David was found dead. Just to refresh everyone's memory, David was Hannah's book editor who we just saw on Girls Season 3 Episode 3 coked out, dancing to LMFAO, punching Ray and cruising Grindr.
The whole scene when Hannah first arrived at their meeting and everyone was running around like mad was a little nuts. I'll admit that I'm a semi-neurotic anxious New Yorker, but I was so on the same page as Hannah when she asked if it was safe to be in the office at that time.
