Damn it but I hate being right.
Panel 1: As Elly lays down on the couch, John shoos the kids away from her and tells them to give her a break because she isn't feeling well.
Panel 2: As they walk down the hall, he explains that she needs a good rest so she's going to bed early.
Panel 3: He then tells her that tomorrow, she's going to relax and take it easy because she's got a day off, m'kay?? Mike says that he does too.
Panel 4: Elly suddenly remembers that the teachers have a professional development day tomorrow; Mike tells her not to worry....
Panel 5: ....because if they bust something, they'll do it quietly; since her face is frozen in the Bug-Eyed Glare of Existential Horror, that doesn't reassure her.
Summary: Like I said, Elly simply cannot rely on John to really handle the kids nor can she expect them to give her a break despite being ill; that's because she's the creation of a woman who is pissed off at her husband and children because their real world demands got in the way of her need to be a self-absorbed jerk.
ETA: On an unrelated note, someone was inspired to write a song about Lynn based on the interview she had with Strombo. Also, the new banner reminds us that John still knows how to have fun.
