You have completely described my Nerd to me. Right now I am frustrated because he is working on a long term project, and I am no longer his bright shiny new toy. He shuts himself off outside on the patio, smoking and working on his project. I am allergic to smoke so he is completely safe from interruptions, veiled by his screen of smoke. He works 18 to 22 hours on this project every day all day, most of the night. Guess Ii have to learn to grin and bear it.
