In my line of work the first thing you learn is how to look busy. You learn that as soon as you arrive on the job site you walk around and point at everything. If you are pointing and measuring people wont realize you are talking about where to go for lunch. The busier you look, the less you have to do. If you have your hands in your pockets you are definitely not busy. If you have a shovel or any type of tool in your hand then people think you are doing something or at least about to. Its actually quite easy to convince people you are busy. I'm not lazy and I do work hard, but when I'm not working hard at least I look like I am.
Haha, bye now.
