When we first met, you sweetly offered the wish that we might become friends. Nothing was easier than becoming your friend, dear Usanda! Your intelligence, kindness, your love of literature, your generosity and the love we both shared for our little Leo, all of it made it a joy to know you.
When I look and hold our beloved grandson, you will always be near me, looking on. Your strong and gentle presence will never leave us. Be at peace, at last!
