Postcard
Each participant will write a postcard to their team, as if they were absent. In a few words, each one will say what they did, liked and will do, all illustrated with a photo. Postcards are always positive, even when it’s raining ;)
Suggestions and variations
Feel free to amplify the humour in your example to get the group to loosen up.
You can change up the activity by asking people to associate 3 keywords with the postcard instead of a text, for example.
