Yes, I cried too... But the difference is... He knows no different. That has been the normal to him his entire life. For us... RSD has taken away part of us... things we USED to be able to do, and now we cant do it.
He is such an inspiration for being positive, but remember he knows no different. This has been his life since he has been born. For us... we had so much before RSD.
Keep your smiles up, and the positive attitude, but dont let it get you down.
