Scenario 5: You look at the beautiful day around you.

Since it is such a glorious day and you don’t need a projector to present your lecture, you decide the first session to be held outside. You put a big note on the door that reads, “Door locked. Class will be held on the back side of the building under the big tree." You wait at the door until it seems that most of the students have arrived and head out to the big tree to conduct class.
