Handy Hint # 6,030,002
Always check the temperature of the water before stepping into the shower.
For instance; if you've been sleeping nightly all bundled up like an eskimo to ward off the winter cold, then you may have developed the following routine: -
turn on the water, strip off six or seven (8,9,10) layers of clothing, (six if you count the socks, seven if you count each sock individually), then step under the spray which is now a comfortable sear-the-skin-off-your-back temperature.
However, if the night has been unseasonably warm, you may wake up to find that in your sleep, you've tossed out of bed nine out of your ten layers of flannelette.
So when you stumble into the bathroom you're wearing very little.
You'll follow your habit of turning on the water, stripping off, (but this time only one flimsy garment), and stepping under the spray, only to find yourself suddenly frozen solid, until the water warms up and thaws you out.
So there it is.
Check the temperature before getting wet!
