April: 'Morning, Grampa! - What are you looking at? Jim: A robin! - See? Over there!... Know what that means? Winter is officially over! April: Really? Guess what, Pop - you're wrong! You said when Mom shaved her legs...it was the first sign of spring!
Interesting that April calls John “Pop” here and a couple daily strips from now (April 17) she calls him “Daddy”. I don’t remember her ever calling him “Pop” before (or since).
