I keep birthday, Christmas, Father's Day or any cards that I receive which are special or funny to me. Since we are moving soon, I needed to clean out my card drawer yesterday and laughed, teared-up, and was thankful for what I found and the people of which it reminded me. I even found a surprise when $10 fell out of a card... a lost little treasure.
So why do we celebrate holidays anyway? Not for earth-quaking changes in our lives, but because of the little treasures.
