思緒分岔

Dear John:
   Oh, How I hate to write! Dear John, I must let you know tonight that my love for you has died away like grass upon the lawn. And tonight I wed another, Dear John.

I was overseas in battle when the postman came to me. He handed me a letter and I was just as happy as I could be, 'cause the fighting was all over and the battles had all been won. But then I opened up that letter and it started:

Won't you please send back my picture? My husband wants it now. When I tell you who I'm wedding, you won't care, do you anyhow? And it hurts me so to tell you that my love for you is gone. But tonight I wed your brother, dear John.
