Should I Be Nervous??

My husband and I took a trip to Menards the other night to purchase new siding for our house. We purchased the house from my parents 14 years ago and have done several upgrades to the inside and outside since then. My father was very good about the maintenance of the house however left the color schemes up to Mom. ( we think she may be somewhat color-blind) The existing siding is a late 70's blue and I have always hated it. It also had a few dents in one corner from basketballs and I think someone at one time hit the corner of the house with their car or snowmobile.
My husband "A" has always been very handy at home projects and will do 99% of things himself . The problem is "there will be an injury" at some point in a project. Either a trip for stitches , a goose egg to the head or a minor cut. I made sure we were well stocked with first aide supplies. I can also assure you that at some point a tool will fly in anger or he will trip over something. I will then have to try as hard as I can to keep a straight face while inquiring about his well-being. I know for a fact that I am not the only person alive who will ask in laughter "Are you okay". My sister-in-law (gambino) is as bad as I am.
He started Saturday afternoon with the assistance of my brother and got two sides ripped off. By this afternoon they had on side resided. I am happy to say that there was only one minor injury. My brother has a small cut on his arm. I was gone most of the day so I can't report on any tools flying.
Although A does good work we have some things that he has started and not fully completed. They are minor and I can live with it but I don't think I can live with a house that is sided on 2 out of 3 sides. (the front is brick). Hopefully by the time the snow flies it'll be complete.
How about those Packers? I think there is a lot of work to be done there. I tried to stay awake for the whole game but got a little bored in the 3rd quarter and hit the sack.
