Say words like so happy to see you today, you are so sweet, so beautiful, so charming, so kind, etc. My son is so lucky to have a wonderful friend like you. My son XXX is kind and generous, work hard, very promising young man. Come back to see me any time at your convenience. Oh, I am just so happy to see you. Today is my happiest day ever. ….
Do not forget to give her a big hug when you see her and when you leave, pat on the girl’s shoulder, smile all the time. … share your personal love story too if possible to ensure the dinner more relax…
Good luck.
