Swimming Lessons

I have the children in semi-private swimming lessons, meaning it's just the two older boys. The instructor said they were doing fine- no behavioral problems, etc. However, he did ask if my boys were this cautious in everything they do. He found it interesting that Christopher wanted to know the physics of swimming before he would do it. See, I do have it harder than some. Christopher wants explanations for most everything he does in life, not that there's anything wrong with that...(Pictures will follow.)
