what is so hard about this?

what is so hard about standing in a certain possession, not talking, and moving you arm back and forth to direct traffic? honestly... what is so hard bout that... i mean if you are at a tech prep program and the thing you are going for is a very professional program... why is something that easy so hard....

it is physically and mentally tiring to stand in one piosition for an extended period of time. between the lack of verying movement and the boredom, it can get quite difficult.
