(Strip Number 4760, Original Publication Date, 10 February 1987)
Panel 1: When Lizzie hands Elly the package of Valentines cards she's willing to get, Elly points out the need for another package because there are more than eighteen kids in her class.
Panel 2: Lizzie sets up the conflict by declaring that it's all good because she's only going to give them to kids she actually likes.
Panel 3: Elly escalates the situation by calling that unfair because she's gotta give them to everyone no matter what they think of her.
Panel 4: Elly is mildly perplexed by Lizzie's terror of having to give a card to the dreaded Melody Morrison.
Summary: This is possibly because she doesn't quite get how stand-offish Lizzie can be. She'll learn, though.
