1. Hello. I would like to thank you a lot, ms/mr ... . I really appreciate that you let me stay here. I'm thankful for the love, the care you showed me. The food and water I was given. I enjoyed experiencing something new: living in another country, even if I didn't remain there my whole life. Thanks.
Love, ...
