If you simply must ride around on a motorcycle without a helmet, I will not feel an ounce of sympathy for you when you get your head bashed in. I guess I can hear either argument about the validity of helmet laws, but they are clearly there mainly to keep the stupidest riders alive.
Walked around today thinking about the novel project. I have a few ideas. The most important thing in the story is that something Happens. An event, a turning point, something interesting and compelling. Life is full of these things… why is it so hard to think of them in a way that works in a novel? But if James Kelman can write an entire book from the first-person perspective of a newly-blind, drunk Scotsman, I can churn out 50 thousand words of whatever comes to my fingertips.
Soon my workplace will be a sea overflowing with miniature candy bars. Resistance is futile, I’m afraid. On Halloween we’re having a big office party in the afternoon, complete with costume contests. I am just going to wear my black gi, white belt, tabi, and a large toy samurai sword. Might put my hair in a topknot, but then that would be mixing my historical references.
Not that anyone would notice. When I say I am a ninja, everyone will ask why I am not wearing a mask, and I will repeatedly explain that ninjas did not wear hoods, enough with the fucking hoods already. Only more politely, of course.

Last Saturday, everyone thought that my Cantonesa Opera costume was some kind of messed-up geisha. Oh, and I am gonna audit a wing chun kung fu class! Not the same as your ninja stuff, but still, ninja stuff.
Did you know that wing chun was invented by a woman? True story! Her name was Yim Wing Chun.
Good luck, that will be a fun art to practice.
