premise: A man sits as a man behind him washes a bus.
hypothesis: The boss is showing a man how to wash the bus while the worker relaxes and enjoys his duplicity.
explanation_1: The two people have no interaction, so no instruction on wash the bus, or one relaxes and enjoys duplicity.
explanation_2: A man sitting as a man behind him washes a bus doesn't mean that the man washing is the boss of the man sitting.
explanation_3: This sitting man may have not been a worker so that would not have been his boss.
