In December, there are lots of Bonenkai, a year-end dinner party, in Japan.
A word Bonenkai means 'In the party, Let's forget everything bad of the year to wlecome a new year happily!'
But, we must be careful what to forget.

Konoyaro Nanda (A fictitious name. 23 years old. Lives in Fushimi ward.) was an organizer of a Bonenkai. She set the party in a restaurant and collected money for it from participants.
When the Bonenkai is over, drunk happily very much, she forgot to pay for a restaurant, and soon went home laughingly!!

All the other participants went into panic, and naturally came to blame her.
They will never forget what happened.
