Absent-Minded

(In my English class, we are taking a quiz while the teacher steps out for a minute to run something down to the library. Suddenly, a late classmate bolts into the room, drops her backpack at her desk, grabs her laptop, and sits down, all within a matter of seconds. We all start giggling, including another teacher sitting in at the time.)

Other Teacher: “That never happened.”

(A few seconds later, our teacher comes back into the room. We all start laughing.)

Teacher: *confused* “What, did you guys not realize I was gone? I was just returning something to the library.”

(None of us bothered to explain, and I don’t believe our teacher even realized the student wasn’t there when she left.)
