the light bulb thing is stupid because it's not like they need to be replaced all the time. if they do need to be replaced all the time, they need to stop buying the cheap bulbs that last for 3 months. they could always _invest_ in LED lights as they work for an average of 50K hours while standard bulbs last for 1K or 2K hours. the bulbs also save on electricity. it would take a while to make up the difference in cost but it's not like the school is going anywhere soon.
