Amusing myself while filling my writing pen after its annual thorough cleaning, with some pondering on the potentially superstitious nature of a writer's chosen instrument.

 There have been times when I ran out of ink, and I wasn't able to refill my pen, and wanted to continue writing,  where I have forced myself to use another pen, despite queasy feelings of its unnaturalness and betrayal;
 but I admit that I would do that writing on scrap paper,  and then properly transcribe it into the manuscript with my true writing instrument as soon as I could.
Is this akin to the athlete who won't play without his lucky socks? Do surgeons insist on using one particular scalpel? A painter's one precious brush? Or is this a special kind of screwy reserved for writers?
