It never fails. My lawnmower breaks down just as I am going to cut the grass. So I lug a bunch of my tools into the backyard and of course I never bring the right ones that I need with me. My spanner wrenches are all back in my basement so I have to go all the way back into the house and even then I have no idea what tools I need. I am not so good with my hands and fixing things in general. I think my next purchase should be a toolbox so at least I can throw everything in there and lug it around instead of going back and forth between the house ten times a day.
At least I am better off than these two.
