(Strip Number 4761, Original Publication Date, 11 February 1987)
Panel 1: We find Lizzie sitting at the kitchen table screaming about the unfairness of having to give a card to the hated Melody Morrison.
Panel 2: Mike comes along and asks what's wrong with this Melody person; Insecure Idiot Lizzie presages Equally Insecure Idiot April's jealousy and hatred of Becky by grumpily calling her perfect.
Panel 3: Mike says that he'd kind of hate to be perfect; Lizzie asks him why.
Panel 4: When he says that he couldn't be anything else, Lizzie tries to work out what that means.
Summary: Lizzie has no real interest in admitting that she hates someone because she makes her feel inadequate. It's why Therese is an ice machine that's jealous for no reason instead of someone who makes Lizardbreath feel like a stupid child.
