This is a kind thank you letter I received on June 9, 2013:
Mom (Barbara), Karla and I had a fantastic four days with you and wanted to thank you again for your hospitality, educating us about Israel, the region, history, politics and of course The Bible, and making so much effort to please us / make sure everything went very well. We are also glad to have become friends and hope that you might have a reason to visit the US again so we can invite you to our home.
Thank you again for everything, your new friends
Barbara, Karla and Brian"
