After our call I looked it up and found more information. During the two weeks when you're secretly leaving gifts for your secret friend (candies or snacks), this action is called “endulzar al amigo secreto” or “to sweeten your secret friend.” The participants should have very creative strategies to give these candies to their secret friends without being caught. At the end of these two weeks, there’s a big party to reveal the secret friend’s identity. There are several ways to reveal your identity. Sometimes people don’t say the names of their secret friends but instead they describe them or even draw them, which is really funny. All participants bring a special present to their secret friends. The present shouldn’t be expensive since sharing with people and having fun are the main goals in this game.
Happy love and friendship month!!!
