If a person is mediocre little is asked of them. If a person good, much is expected of them. If a person excels much is demanded of them. Is that fair? No, but for all practicle purposes this is how life goes. People soon learn that if you need something done, find the busiest person you know because they always have a way of getting things done.

Perhaps you might be a tad bit less frustrated if you look at this like a compliment. Just a different perspective...
