Mathematician waiting for the wedding cake and the cava at the reception

Abstract

Imagine you are at a wedding reception. You have been sitting at the table for two bours and the cave, the cake and the coffee still must be brought. You know nobody except your partner. The interesting conversations and the good jokes have already been told, and you don't even remember the name of more than half of the people sitting at your table. Although the guests don't believe it, mathematics has been present during the meeting, and you, of course, are going to tell some stories about mathematics and what you have just eaten. Some of your comparations porbably will leave when you start, but those who stay may have an enjoyable time and may even learn something new. The volume of alcohol ingested by all of you might influence the development of the exposition. Drink in moderation and wait for the dancing and the free bar for to start being yourself
