That is so excellent! I was deeply touched by the picture of them both working on the model together, your sons small hand and your husbands adult hand. You should be very proud, not only of your son, but of your wonderful family that is delivering such a cutting edge education your son will benefit from as he pursues his goals as an adult. So few children are getting that education today, and the change in how things are made is so significant, I feel very strongly that lack of opportunity is a tragedy. Fortunately, your families wisdom is ensuring your children will not suffer that lack of understanding that will hold so many others back from achieving their dreams.
Thanks!
