Broken hearted

My heart is broken.  Nathan came home from school today and you can tell he had been talking about cars and driving.  Lately, he has been very interested in keys.  His teacher gave him an old set of keys to come home with and was asking lots of questions.  One of the questions was about how to take a driving test.  He became very upset because his teacher reminded him that a person has to take the test alone in order to pass.  He kept saying “but I am blind and can’t see so can you please help me take the test?”  I didn’t answer right away, I was trying to find the right words.  He then asked if I was blind like him would I be able to drive?  I explained to Nathan that unfortunately when someone is blind they cannot drive and he said “what about an automatic car?”  I said absolutely!  I will NOT let Nathan believe it is not possible.  He went on to tell me how all he wants to do when he grows up is be able to drive, get married and have kids.  He literally talks about getting married all the time!  How would I ever take that away from him.  We do not discourage this idea, we just tell him he has to wait until he is older.  I never want him to feel like he won’t be able to have a love like that.  It is days like these where I physically want to throw up from the thought of his future.  It is also days like this, that I hold him a little closer and thank God for the gift of him.
