I am not an english native speaker. Please help me. Thanks in advance. I am writing a thank you note to my mom-in-law who sent me best wishes for our wedding.  Have you and she agreed that you will call her "Mom"? Dear Mom, Thank you for the beautiful card and for all your love, support and wishes. I am really touched. I cannot wait to see you. My parents return your regards. ( not sure how I'd return her regards she extended to all my family As you have it is fine.).   Love, Tina   Is there anything else I could write to make her feel nice?? Thanks once again.  It's a bit short. Do you have any news about the wedding you can tell her, or about what you and your husband have been doing? Imagine you are sitting with her and think what you could be saying to her.
