It's been a long time not to see you.
I've heard that you come to visit me yesterday while I was not at home. It’s such a pity that I was just outside with in my office with my business by that time. I'm sorry that I didn't get a chance to meet you. How are you and your family these days? Is everything goes well? I do miss you a lot and hope to enjoy a good time with you next time. Please let me know if you are available. Looking forward to hearing from you.
