um, sometimes it isnt as simple as changing a bulb.
ps-if you paid someone to come change a burnt out light bulb in your own home, how much do you think it would be fair to pay them for their labor?? play along. i know it soudns absurd, but nothing is free, not even calling an electrician to change a light bulb. yep, you may have a neighbor who will gladly do it for free, but assuming you HAVE to call an electrician for whatever reason, what's the "fair" price?
do you see the point or is it going above your head, like you claim the other stuff is going above other posters heads??????
