Do you own a red pen? I have a bunch of pens that are black, a few that are blue, and not a single red one in the house. I want to use the red pen to mark a special set of files. Seems a little strange to get in the car and drive to the store just to buy a red pen. Maybe I’ll just do something else for the rest of the day and wait to pick up a red pen tomorrow on my way to the office.
