It's been a while since I asked you to take out a clean sheet of paper.
Take out a clean sheet of paper. Write "The last time I saw you" at the top.
Now, finish the sentence. Then, write five more sentences. You can make this a poem for a parent, a note to an old friend, a prayer for your first love. Whatever you want.
When you're done, burn it. Or mail it. You're creative -- you'll know which way to go!
