This first step is admitting you have a dork problem. For example:
Today, at a table outside the library at which we were handing out pens, calendars, and water to students on their first day of class, our organizer noticed were out of pens and she started pulling out more pens out of a bag, as if by magic. I commented, “Wow, it is like you very own bag of holding.”
My mouth froze in horror. My inner dork was revealed! Then, one of the guys at the table smiled at me in understanding. We had a conversation about how cool it would be if we really could have a bag of holding and what we would like to put in said bag.
–Jane, maybe a few bottles of Sauvignon Blanc?
