This year I decided to repeat this activity I had done three years ago (explained here). This is what I wrote in that article:
Some days later I came accross this beautiful article thanks to my friend Laura Martín. The article appeared in the blog Zen Habits and talks about how much money we spend on Christmas presents and gives advice on how we could share costless things with our beloved ones. And I thought, why don’t we have our zen presents in class? And so this activity was born.
