empty cans

i'm sure most of you have met in one point or another in your lives , a person, who thinks they are so smart and good but they fail to deliver time and time again.

i have a few.
but to add more insult, the ones i know are rude and arrogant.

help them save a few hours and there not even a word of thank you, instead, they make as through like its my fault.

well, there wont be a life line for you ever again.
i guess its true, empty cans make the most noise
