Dating dates back to time immemorial when lovers used to type on rocks and sisal love messages. Back then it was a taboo being seen with somebody's daughter and especially if both parents had not arranged for it.
Funny enough were bush dates or dates along river banks especially when she had gone to fetch water or look for firewood in a nearby bush. Most often men could alert their lovers with funny whistles or throwing stones all in the name of making their lovers to be aware of their presence.
