I was ready to kill my kids when the bulb burned out in my range hood.  I had been on them for the life of the bulb about how expensive and hard to find these bulbs are.  Often they cost $6 or more each.  Now I have 10 of them and the light in my hood works again.  Peace has been restored in my home as I now have 8 spares and the kids still cant turn off a switch.  Why is it a kid can turn every light on, but is completely incapable of turning any light out?
