Burros have amazing stamina

Dear Pedro, I heard that burros have amazing stamina. Do you hike a lot? Or does The Boss think that dragging that mailbag counts as a workout?

We burros are an amazing lot, Gautam, but I don’t hike unless I’m on a food search. The Boss says dragging the mailbag counts as a job and that I can work out on my own time (ain’t gonna happen).
