Hide-and-seek 
Why did you undo my edit to the caption on the image in this article? The image does not show children playing; this is patently not true. The image shows an oil painting from the 1800s. Since when have paintings (the physical manifestations of the painters' singular and subjective perception of the world) become accepted as sufficient encyclopedic documentation of a real-life occurence - in this particular instance a moment from a game of hide-and-seek? 92.26.222.89
