The bulb burned out and when I tried to replace it I found it was stuck. So I used just a little elbow grease, and the socket came loose. So now it all turns round and round, and the bulb still doesn't come out. I don't want to twist the dratted wires off. And I can't grip the socket, because it's all tucked inside a pretty little glass shade. So how do I get the whole thing apart and then back together properly?
