I realize this strip is out of sync with the times.  It kinda ignores the pandemic and remote schooling.

This really happened during the pandemic.
Luna was sick for a couple days and didn’t have to do the remote schooling (which she hates).  She then tried to fein illness a third day to get out of class again. 
Kate said, ” No no no.  Talk to me if you’re dead.  Otherwise, you’re going to school.”
That’s how strip ideas are born.
