Another classic activity during this celebration, particularly among young students, but also among other general groups (coworkers, companies, civil organizations, etc.), is the game of the "invisible friend", which is a variation of the popular Secret Santa. One week before the celebration, participants are invited to write their names on a piece of paper and then, after scrambling all these pieces in a basket or container, retrieve one of the names, without revealing it to the others. Participants then become the "invisible friend" of the person on that piece of paper, and during the week before the celebration, they are invited to write anonymous small notes or letters to the person whose name they selected. On the day of the celebration, invisible friends bring presents to their friends, and one after the other, reveal their identities before giving their presents.
