I had a day like that a bit ago shortly after i started kendo. So i'm heading up to the coffee shop to get my daily fix.. when i see some older teen/early 20's guy walking up the street with a bokken. I fall instep behind him thinking, "hey.. there's someone from class i haven't met before, he must be one of the iaido guys." And what does he do? walks into my coffee shop ahead of me. Great! So i get in line behind him and ask, "Iaido?" blink blink I gesture at his sword... "oh.. no.. it's a bokken" /sigh "No.. do you do Iaido? I don't recognize you from kendo class" i clarify. "um.. no" he says, "this is just for the walk home." I've called it my first real ninja siting since then.
