LOL about the tangled lights. My parents finally bought a nice, pre-lit tree this year to avoid the tangled light issue... at least where the main Christmas tree is concerned. Dealing with the lights is always my Dad's job, and this year he'd had enough. We put the tree up when I was home over Thanksgiving, and I have to say it was great... it was significantly less stressful.
But, we also have a few smaller trees here and there in the house and some lights on garlanding, outside, etc. So, for those extra decorations he still needs to confront the loose light strings.
