You're serious?
Any office clerk will need to write permanently, filling forms, making notes or memos, or signing documents, for which pencil is inappropriate. An executive on any level, not just a lawyer, would need a pen for this even more than the clerk.
I carry a pocket notepad and pen routinely, for notes that a pencil would not write nearly as well, given the small size of the pages.
I get together with Collucci about every week at a local diner, and one of the first things he does after we settle in and order our food is turn the paper placemat over, pull out his bullet pen, and sketch something -- generally a knife idea.
Literacy. What a concept.
Yes, I was serious, not trying to be a smart ass. Having spent my life as a blue collar tradesmen I don't think in terms of office work. In the machine shop we always used pencil for the math on the side of the drawing. I'm just used to using a pencil I guess.
Sorry if I offended your concept of literacy or something!
