For a master painter... Painting a very small house is easy, painting a mansion can be difficult, or hard. Painting 5 houses in one day even more difficult. The way the man paints hasn't changed between the houses... But the extremely long task place before him could be considered "hard".
A man licking envelopes for a living is a cake walk job, that doesn't take any skill. But after a 10 hour shift... He still has completed a "hard days work". Was what he did hard? Nope, but committing to it for a 10 hour shift 5 days a week, was pretty hard. LMAO
