Seeing the expression on his face when he realizes why you are here.
Watching him fight the tears and feelings of disbelief as he looks at pictures of your family and his new reality refreshes its impression on his young mind.
Seeing the tremor of excitement shake his body when each beloved caregiver passes by with a joyful smile and stops for a consensual hug.
The stunned look of, "Is this really real?" intertwined with pure happiness.
All the uncertainty of the past year falls away as a young boy is given hope and the love that he deserves.
