We have an artificial tree as my son and I have allergies. Two years ago I bought a new tree that already has lights on it as I hate putting the lights on. It looks really good. Anyway, this thing is such a pain to put up because the limbs are very scratchy. I now have scratches on both my forearms. Next year I need to remember to put on long sleeves before putting up the tree. I got the tree up, plugged in the lights, and it looked great. Yesterday evening I plugged the tree and some of the lights were not on. It says on the box that a light can go out and still the others are supposed to work. So I was definitely upset about that. Instead of wasting my time trying to find out if one was not working (as there are a lot), I just decided not to worry about. I finished decorating it today and it looks really nice. I'm not even sure if anyone will notice if I don't tell them. BUT STILL, it is very irritating for something like that to happen.
I came back to add that my husband does the outside decorations and it is better to leave him alone and not even try to help. When the kids were small, I tried to keep them in house or they would learn a new language. ;-)
