Today is the Mid-Autumn Festival. What should I say when I call my girlfriend's father?

Hello uncle or uncle, I'm calling to wish you a happy holiday! How have you been recently? Pay more attention to your health and don't be too tired .. We (I) are really sorry that we can't go to see you. (Look at the expression) We'll go back to see you as soon as we have time ... and tell him that you are fine, don't say sweet words, be sincere ... I'll help you, because I know you are a man, and you certainly don't know what to say. Sincerity is the most important thing. Well, I wish you all the best.
