Hi again all,
Thank you again for all your help. I'd like to send a short message to my girlfriend's mother who has been sick. I know her name is Nga but am not sure how to address her. Please Help me.

Dear ____,
Thank you for treating me so well everytime I come to Viet Nam. I pray you get well soon. I look forward to seeing you again. Wish you always happy.
Sincerely,
Joe
