Rohan and Ekta go out to dinner. They invite 3 other couples. When everyone arrives they greet each other and some even shake hands with one another. However, no one shook hands with his or her own spouse.
At the end of the dinner, Rohan asks all the attendees "How many people did you shake hands with?"
They all reply with a number. The numbers are: 0, 1, 2, 3, 4, 5, 6.
