Phil refuses to kiss and tell owing to an old-fashioned need to not boast about his sex life; this infuriates Elly because she lives for gossip and wants to know what she can hold over his head.
Panel 1: Elly angrily asks Phil where he's been as if it's her business.
Panel 2: He tells he that he took Connie to the New Year's Eve party at her work.
Panel 3: And THAT, Elly....
Panel 4: ...is,as he pats you on the head like a dimwitted kid, all he's going to tell you. Her not knowing what he did is going to eat at her forever.
Summary: Remember, folks. Everything is about how she feels; nobody else matters but her. She doesn't give a shit what he did with Connie, only that she doesn't know which way to panic.
Anyway, tomorrow she wishes the holidays had gotten over quicker so she could go back to her regular nonproductive busywork.
