He will always be 15 years old.

That to me is what's most painful - that as Menachem and Chana get older and become complete adults, and as his classmates progress and graduate high school in a little more than three years to disperse and to coninue their educations and start their own families and careers, Avi will remain behind forever at 15, becoming a fading memory...

I watched Avi slip away once...I can't let him slip away again.
