My stupidness begins 4 months back when I unbolted my windscreen wipers to replace the rubber easily. Tighten the passengers side bolt but only hand tightened the drivers side.
Drove to my grandmothers 40 miles away to pick up my Chrimbo present.
Drove back late at night and yes it began to rain on a dual carriageway in the middle of nowhere.
My wiper last 3 wipes before launching itself off the screen and flapping everywhere. I drove another 20 miles leaning over the passengers side to see where I'm going.
Finally made it home with a stiff neck so I decide to cheer myself up and open my present which happened to turn out to be a.............damn multitool!
