One of the greatest gifts my dad has given me is a deep appreciation for what I have and heartfelt gratitude to those who have given it to me.
I described the changing of the guard at the Tomb of the Unknown Soldier to my students, and one responded, "Who cares if they can walk a certain number of steps?" (I know, don't get me started). I replied that it had nothing to do with who cared if they could do it. They do it because they care.
As we all should.
