Hee! Next time, set a timer? My microwave timer can be set to go for a good long time and it is loud enough when it goes off that I hear it elswehere in the house. This is how I keep from watering the garden for 72 consecutive hours (when I remember to water the garden at all, that is.) Of course, then there's the moment when the timer goes off and you can't remember what you set it for, and you're hunting about the kitchen for something left on, but that's another story!
