An infinite loop problem can be used as a joke. Who can help me find it?

One day, the boss called his secretary: I'll take you to Beijing to play these days, so be prepared.

So the secretary called her husband: I'm going to Beijing to have a meeting with my boss these days.

So the husband called his lover: My wife is not at home these days, come to my house quickly.

So the lover called the tutor: the teacher has something to do these days, and classes are closed!

So the tutor called grandpa: I don't have classes these days, and grandpa took me to play.

So grandpa called his secretary: I can't go to Beijing, and my grandson wants me to accompany him.

So the secretary called her husband: the boss suddenly had something to do and didn't go to Beijing for a meeting.

So the husband called his lover: My wife is not leaving, don't come to my house, we'll talk about it next time.

So the lover called the tutor: you can have classes as usual these days!

So the tutor called grandpa: Teacher 5555 said that classes would be held as usual these days.

So grandpa called his secretary and said, let's go to Beijing. Get ready.
