We stayed in a gorgeous luxury beach house in Dunsborough one time, which was absolutely beautiful -- except that the toaster was placed right under the smoke alarm, and the darn thing went off if you even heated a slice of bread. To make things funnier, the smoke alarm was about 35 feet in the air (well it looked like it to me) and hubby had to use a broom to shut it up. Still, better some inconvenience than a house fire!
So, if you haven't checked your smoke alarm batteries, get up RIGHT NOW and go do it. And if you don't have any smoke alarms -- WHY NOT????
