What psychology is it to send text messages to mom?

In fact, parents are realistic, and text messages can only make your girlfriend's parents feel warm. It is impossible to prove that you are a manager just by a short message. The following is a short message.

Aunt xxx, I wish you a happy Mother's Day. I hope you will have a permanent appearance and good health! At the same time, I hope aunt xxx can trust me to take care of xxx (your girlfriend's nickname), and I will do my best to take care of him and care for him like you. Then write your own name, the writing is too gorgeous but flashy! )
