Panel 2: Oh, for crying out loud. She's shocked that people showed up at her garage sale? I can kind of understand if that one shadow is actually grabbing the lamp, but in that case, it's perfectly acceptable to bark at someone.
Panel 3: Ha, she's selling wrapping paper! And LPs? Surely she could get more for them at a used record store, unless they're like, Leo Sayer's Greatest Hits from K-Tel. Actually, I think I have my answer.
Panel 4: Guess someone likes Leo Sayer then! Or perhaps they're into shooting skeet.
Panel 5: More mutant Milborovians.
Panel 6: Whoa -- April looks anime! All she needs is the eye sparkles. And judging by advance reports, I guess she's going to suffer for this. Like such a thing never has happened. Or as if Elly could not have thought ahead, and brought nothing outside that she could not risk. That said, April sold a coffee cup with coffee IN IT?
Panel 7: Oh, I see how it goes. They probably told her "Everything. No, EVERYTHING! Just DO IT!"
Panel 8: Well, okay, that I have more trouble with. Surely she would have known what the calculator was being used for.
Panel 9: Okay, Lynn, I give. Teenagers are useless, especially April, I'm glad she's not my kid, she had this coming, yadda yadda.
