"Oh Shit" moments...

Ditto that.

Got this awesome swiss army knife for my tenth birthday from a relative. My mum was none too chuffed. I promptly displayed my prowess and how I could easily be trusted by snapping it shut on my thumb leaving me with a scar today some fifteen years later from the tip down to the joint.

Much blood and shrieking later and she'd finally calmed down.

I tried to hide the wound by putting my hand in my pocket....I think it made my mum's shock worse when she saw me saunter past with one leg of my jeans soaked in blood pretending all was right with the world.
