I never thought of them that way, and I don’t have much occasion to use them, so I don’t keep them handy. Something happened to change that. And no, nobody has taken my sharp objects away from me — yet.
A colleague for whom I do freelance work sent me to court as an observer in a case that indirectly affected his client, with instructions to take copious notes. While I was taking the notes, my pen ran out of ink. I switched to the only other pen in my backpack. A few words later, it also ran out of ink. I knew some of the attorneys in the room, but none were within nudging distance. They probably would not have appreciated the interruption anyway.
I kept taking notes anyway, pressing the pen down as hard as I could so that I would be able to read the impressions later.
Afterwards, someone I shared this trauma with suggested I rub the pages with a crayon to improve the readability of the impressions. It worked.
I was annoyed at having to buy a whole box when I only needed one, but they may come in handy when there are kids in the waiting room — or if my sharp objects are ever confiscated.
