Mysterious Guest

During the O Games, my friend’s family of three will be coming. He will be bringing another family of three. All six of them will be staying with us for a week. My friends’ friend has a very rare last name that totally rings a loud bell to me my former colleague has the same last name. He also has two daughters. That's all I know about my mysterious guest. So I emailed my colleague today asking if that was him coming for a surprise visit.

I have picked up friend from across-continent flight and by chitchatting at the park. I have made several ever-lasting friends through my other friends. Being a highly suspicious person, I am also extremely lucky. I heard complaints that it's difficult to make friends. I think if you open the door, they will come.
