It is to the person you're being polite to: he has no idea what's going on in your head. Of course, that still might not save you, as
@US Blues point out.
My dad taking us to job-sites is one of the reasons I became an engineer. I still remember one Saturday he was supervising a crew lifting an air handler to the roof of a building he was building. With a helicopter. How cool is that for an eight year old to see? All the refineries and chemical plants down here used to host Family Day when everyone got to come out and see where Dad worked (not too many Moms in the plants then). By the time I started that tradition had gone by the wayside. I did get to have my kids out to watch a crane crew I was working with lift a couple of 50 ton skids off their over-the-road trucks and onto trucks which could navigate our plant. The facility guards really went out of their for them, too: gave them hard hats and fire retardant clothes and safety glasses. My six year old daughter and three year old son looked really cute standing with their faces pressed up to the chain link fence with their fingers in the holes (I mean who
doesn't do that?) and their Nomex lab coats drooping all the way to their ankles. They've only got to see where I work one other time, but that's another story. That story ends with an arrest (not me).
