I have only one question?
WHY DO THE MIDDLE STRAND OF LIGHTS ALWAYS HAVE TO GO OUT ON THE TREE?
No, not the top one, nor the bottom one. ALWAYS the damn middle one. I refuse to try and track down the broke or loose bulb, I just throw another strand over the old dead one.
Soon, there will be fifteen strands overlapping each other....then it will be time to throw out the tree and start anew.
