This post brings together the four images in the “orange sequence”.

A woman writes her number on the skin of an orange

She then throws it in to the river where it will be picked out by a man

The orange, having been peeled by the recipient

The man then tastes the orange. If it's sweet it bodes well and he'll call the number written on the skin of the orange, sour - not so well (and you'd figure he wouldn't call).
