Abraham Lincoln 
Three sons died. Edward 4, William 11 and Thomas 18. 
In this world of ours, sorrow come to
all........it comes with bittersweet agony

I am anxious to afford some alleviation
of your present distress.

Perfect relief is not possible, expect with time. You cannot now realize that you will ever feel better.

And yet it is a mistake. You are sure to be happy again. To know this, which is certainly true, will make you some less miserable now.

I have had experience enough to know what I say.
