-In Shakespeare's time, mattresses were secured on bed frames by ropes. When you pulled the ropes, the mattress tightened, making the bed firmer to sleep on. Thus, "Goodnight, sleep tight." (I bet those ropes could double for some kinky bondage . . . just sayin' . . . )
-In Babylon, it was an accepted practice that for a month after a wedding, the bride's father would supply his son-in-law with all the mead he could drink. Mead is a honey beer, and because their calendar was lunar based, this period was called the honey month. Thus, "honeymoon."
I just thought these few things were interesting and worth noting. If true, anyway.
