Keep waiting till infinity!

I don't understand why some people think that others don't have any work other than waiting for them .
I think they need to go back and look up in the Webster dictionary or whatever is nearby them and try to understand that we have some words like commitment , promises , values and punctuality .
They think that they can getaway with anything as they were busiest person on the earth .And if they would not have finished their "so important " work it might lead to a nuclear war. C"Mon give me a break people , please go back and get some lessons of punctuality and timeliness and get out from their self obsessed world to become more humane and benevolent.
