Dear Benter,
  You have been away exactly two weeks today but it seems more like two years to me!
  I’m glad to hear you’ll be back soon. Are you coming directly home, dear? Or do you plan to make some stops   36  the way? I hope you’ll be home in  37 for Patsy’s birthday next Sunday. She is  38 you to show films to her  39 friends.
Patsy keeps asking every day  40 you’ll be back. She says you never  41  that story you were telling her about  42 train that lost its “ toot”(喇叭嘟嘟声). You’d better   43  and think up a good ending  44 it. You know how Patsy is? She  45 be happy until she knows exactly what ­__46  to the “toot” and  47 the little train got it back  48 !
  Everything at home is fine except that we  49 you so much! I’ve been  50 with the spring cleaning. Yesterday I had Cora  51 in to wash the kitchen walls and she did a very good __52 of it. The kitchen looks as though it’s been repainted. I made some new yellow curtains, and they  53 very beautiful.
  I went to see your mother yesterday. Her  54 is all gone and she looks very  55 . Your sister Jean looks wonderful! She has taken off about fifteen pounds since she began dieting. But now she’s complaining that none of her clothes fit!
Hope to see you before next Sunday.
  Love and kisses to you!
                      Yours
                            Lynn
