Do not keep the alabaster box of your friendship sealed up until your friends are dead. Fill their lives with sweetness. Speak approving, cheering words while their ears can hear them, and while their hearts can be thrilled and made happier. The kind of things you mean to say when they are gone, say before they go.
Fifty years from now it will not matter what kind of car you drove, what kind of house you lived in, how much you had in your bank account or what your clothes looked like. But the world may be a little better place because you were important in the life of a child.
