Parents send invitations to their sons, but their sons don't go.

I'm sorry I can't attend your wedding. I want to express my best wishes to you on the phone. I wish you a happy marriage and an early birth. I will also send my best wishes to you in the distance. I'm glad to receive your wedding invitation, but I'm sorry that I can't attend your wedding, because there are some personal matters at home that need urgent treatment. Here, I wish you a happy wedding and a happy marriage for a hundred years.
