It's been so fun to watch the progress that Jake has made on our house. Last Saturday was his birthday. I asked him what he wanted to do, and he said he wanted to work on the house. So, we bypassed an opportunity to sleep in and dressed for the cold. We worked on the upstairs (outside) walls. Jake cut the wood and I nailed two by fours and stapled plywood sheeting. (I only made a few mistakes.) I guess I don't have a lot of upper body strength. After three hours, my arms and hands were sore from the weight of the nail gun. I wish I had more free time, because I really enjoyed working on the house. The only part I disliked was sweeping. Why do you have to keep a construction site swept anyway?
