Dear __________,
You are an incredibly loving, giving, and devoted mother-in-law. As I think of you, I can almost see your warm glowing smile. I remember how the first time we met, you instantly made me feel comfortable, and welcomed me to the family with open arms. That day I realized how much sweetness there is in your family, and how lucky I am to be a part of it. Thank you so much for your love and kindness. Happy Mother’s Day.
