Panel 1: We start things off with Brandy whispering as she asks Dawn, Liz and Shawna-Marie what they think of Miss Edwards. Dawn thinks she's strict, Liz thinks she's nice and Shawna Marie thinks she's pretty.
Panel 2: They then raise their voices a bit so that Brandy can ask if she'll get married, Dawn asking if she even has a social life and Liz wondering how old she is.
Panel 3: Since the girls have forgotten that having one disability doesn't mean having all of the disabilities, they kind of freeze when Miss Edwards wheels over and ask if they had any trouble with the test. They lie and say no.
Panel 4: Since we're being beaten over the head with the idea that most of Liz's problem with school is focusing on the wrong things, they look stupid when Edwards tells them that if there's something they wanna know, they can just come right up and ask.
Summary: First off, no one who ever says that really means it. Second, we're dealing with the whole "get your head in the game and stop worrying about your social life" thing parents like to tell kids. Third, Lynn loves her some old-timey sitcom jokes, eh?
