Panel 1: Elly reminds us that she didn't get any sleep last night because April can't tell time; this means that she isn't getting up just yet. Things should end there because Sue is going to sympathize with her taking a 'me' day but they do not.
Panel 2: What happens is that Elly is up but she isn't going to get dressed.
Panel 3: As she gets dressed, she tells herself that she isn't going to go to work that day.
Panel 4: At the library, she amazes herself by what she can do with the right attitude.
Summary: What appeals to most people is the universality of this one. Everyone has had days like this. Just don't tell Elly....she doesn't like thinking that she's just like everyone else.
