Behold the Mighty Water-Bottle
Which grants us warmth from foot to head.
But lo, towards morn, it cooleth off,
And must be pushed from out the bed.
I remember hearing recommendations that we use hot water bottles this winter in order to survive the lower thermostat levels caused by the money-grubbing folks who sold us natural gas in the US. Now, for some of you, lows in the upper 30s and highs around 50 may not sound so bad, but remember that we have no central heating, just a sketchy electric heater that we turn off before going to sleep.
So the hot water bottle is a life saver.
