(Strip Number 4626, Original Publication Date, 4 June 1986)
Panel 1: When she notes a piece of paper with signatures on it on the table, Lizzie asks Mike what it is. He tells her that it's a petition that Mom's getting people to sign.
Panel 2: When she starts to sign it, Mike warns her not to sign something unless she knows what it's about.
Panel 3: When she asks him what it's about, he says it's about some old building someplace.
Panel 4: Since she's five, knowing what it's about is good enough a reason to sign it.
Summary: This is the first broad hint that Mike sees this whole deal as yet another means by which Mom can embarrass him in front of the other irrelevant children whose opinion is supposed to matter more than his mother's need to find out who she is. Also, Aaron must not have been as gung-ho about the move as Lynn wanted him to be.
