Not what other people are doing
i dont think many people crash professional conferences of this type. It was as accessible as making a duplicating of one of the name tags. And being nice to the charming other participants.
My charming nefarious accomplice Mz Abigirl and i watlzed into the Presidents reception, enjoyed the fancy food and hobnobbed with some of the other participants until one of the apparent organizers of the event did not seem to recognize my name from my nametag. Perhaps next time i pull this stunt i will be Pat.
