(Strip Number 4737, Original Publication Date, 2 January 1987)
Panel 1: After dinner, Connie says that she can no longer stand the suspense and tells John and Elly that she and Greg have big news.
Panel 2: Said big news is that last week, she and Greg got married; they didn't tell anyone, they just upped and got hitched.
Panel 3: Elly stammers as she asks what made them to decide to do so.
Panel 4: When Greg says "EASY! She proposed and I accepted," Elly and John are surprised.
Summary: This is because of this whole "the man is supposed to do that" thing they're used to. A woman isn't 'supposed' to be as 'forward' as this despite it not really mattering much.
