pen

So whats the deal with the little ladies who wear a pen on a chain around their neck? I can understand wearing your glasses on a chain. You really need your glasses and sometimes you might forget where you put them. But a pen? On a chain? around your neck? Is there a need for this? Like, maybe you might run into a fed ex guy and UNEXPECTEDLY be asked to sign for something? Or maybe you were working on a crossword puzzle and you might SUDDENLY think of the answer to 5 across? Maybe its a germ phobia type thing? Maybe these ladies are asked to sign in before they can get on the elevator for work and they don't want to use that icky soiled pen that everyone else has touched?

This pen around the neck thing has been bothering me for a few days now. Weird, i know...but i cant let it go. CAN SOMEBODY TELL ME WHYYYYYYYYYYYYYYYYYYYYYYYY????
