You are 14 years old and the year of the school is finished and all do a big party. All Your friends are in the same age and so You do know all games and jokes and fun and understanding of Your teen age. But when You are in room as youngster with old humans or You are a grandfather and You have to stay with kids, then You will be bored. So in the restaurants or theatres or discos, You can see old people or young people but they don date the other group. But now there is the situation, a wedding or a birthday and nobody is around at Your age. So You hate to bore Yourself. So I tell You how to have fun as youngster with old people and how to have fun as grandma with kids. So the biggest mistake is to wait until it will happen. So the youngster will laugh a lot with old people when You start to play a game with them like chess. And when You are a grandma and You wannt contact young people, then use the music. Cause music is some millions years old and young and old people love to dance.
