Answer:
Dear Chucks,
Ages since I heard from you - do hope that "no news is good news"! Very sorry to have missed you on your last visit, I had only just gone to Enugu when you arrived.
Here's your book again - many thanks. Have been feeling a bit guilty about not sending it before, but you know how it is. I liked it a lot, as you said I would. Didn't like the ending though. I still think that Ben should have escaped the heroine's lovely clutches! He really didn't deserve a fate worse than death, like marriage. Still, we know what we would have done, don't we, City Boy?
See you in the holidays. Best wishes to all your people. Don't let Lagos get you down!
Yours ever,
Sunny.
