Hi,
Tonny!
How are you?

  Sorry, but I have a bad news for you. I lost your favourite book yesterday evening. It happened accidentally, I am sure.

   I walked down in the park. And it was so cold that I decided to get my jacket out of my bag. My jacket was the very bottom of my bag.
I laid all my things out (and your book too) and then forgot to get it back there.

   I am feeling myself very stupid now. Tell me please can I buy you the same book? I will try to find it.
Waiting your answer,
Jack.
