Drifting and dreaming again

Can I say anything at all to a public audience on a postcard? Maybe, postcards only work when one has an emotional tie to the recipient.

Can I explain how the cold gray sky and the snow blowing from the west do not bother me now that it is March again? Why would you care if I could? Can I describe the arms I imagine wrapped round me—or the smile and eyes that light the world—in a mere postcard?
