At this sad moment, I am very grateful to you and your team for your condolences and support when my old man died. Your concern and generosity make me feel very warm and moved.

I know that you and your team are also very busy these days, but we are very grateful that you still took the time to visit me and my family. Your sympathy and support make us no longer feel lonely and make us feel that someone is around.

I also want to thank you for your gift. Although this is not my main concern, I know your thoughts and concerns. I will always remember this gift in my heart. It represents your friendship and support.
