Replace the dimmer switch with a normal switch. This will a) eliminate the argument, b) eliminate the nasty buzzing noise that dimmer switches cause (see the Wikipedia article referred to above), c) allow you to use energy-saving bulbs if you're that concerned.

Personally I find the cost of running standard 60W or 100W bulbs is so low, I don't tend to worry about it. Having said that, I do generally turn lights off when not in use.

An often-underestimated threat to bulb life is the design of a lampshade. Bulbs running too hot because they are 'too enclosed' will burn out much more quickly. (This is one reason why you shouldn't exceed the max wattage rating printed on the lampshade - you could end up with meltiness, or a fire!) If you ever find a particular light in the house keeps blowing, it's often worth checking how hot the bulb and its surroundings are getting.
