Ran out of fuel, just coming off the freeway (thanks to the guy upstairs that it didn't happen while overtaking on the freeway). Remembered (this time - pushed the sodding thing about half a km up hill last time I ran out because I was newly back to biking and forgot) the existence of the reserve and rode to the servo to fill up. Got on and rode out, only to realise I hadn't buckled my helmet. Pulled over, gloved off, did that, admonished myself: "OK, focus now, no more screwups...", gloved on again and rode home (I'm sure there was a 'forgetting to dig the keys out of the pocket before putting the gloves on' in the sequence somewhere too). Got home, went to casually kick the sidestand, missed and had the bike fall over. Stopped it from hitting the ground (will feel it tomorrow) but hit my head on the side of the garage in the process (but not hard enough to ding the plaster, so hopefully not hard enough to require the purchase of a new helmet). The bike's staying in the shed until tomorrow - my reflexes, nerves and attention are clearly just not up to the task today.
