Most of the times that a student rushes into class late or fails to hand in their homework, it's not because their dog ate their essay, or they almost got hit by a bus, it's because they simply didn't do the work.
On top of the actual work of teaching, many teachers become experts at detecting fabricated excuses from bizarre truths. While many of the wildest excuses are pure fiction, there are times when a student is late because life is endless chaos.
I was a teacher (college) but my students were mostly good. Oddest excuse was someone was late to lab and normally if you missed the opening slides/presentation detailing today's experiment you could not take the class that day. This was as much a safety concern as anything else. Once a student burst into the room just as I was finishing the slides so they were technically okay. When prompted for a reason they said they had lost track of time squirrel fishing. Considering they still had the stick, string, and nuts in hand I let them go.
