I left at full sunshine and completely forgot to bring my bicycle’s headlamp. The taillight is always on the bike, but the front one gets charged in the house after every trip. Luckily, I found a torch and roll of duct tape in my hiking backpack. It finally paid off that I always carry all this silly gear around.
A few weeks ago, I actually thought about removing the torch, because it’s been a hot minute when I last used it. Fortunately, I did not. :-)
