Sitting next to a bored child on a plane can be an interesting experience. When they are cooped up in a confined space over a long period of time, they have to keep themselves entertained somehow.
One woman didn't expect to be the entertainment herself when she realised her sock had been used as a canvas while she was asleep.
Passenger Julia Valentine, who often shares pictures from her travels on Instagram, had taken her shoes off and placed them into the gap between the wall of the plane and the seat in front while she slept.
