I wholeheartedly agree!
I tend to find new college grads want to pair up and code together. What's that about?!? It's not like they produce more code sitting hip to hip. When one of them sat down to "help" me, my production went down, because my thoughts kept getting interrupted by, "you need to do this..." "place a brace over there..." etc.
I enjoy teaching newbies, but there is a time for training, and a time for me to get my work done. I don't like someone else looking at my screen, thinking and TALKING about the small piece of code, while I'm busy thinking about the big picture design and API.
