Listen to others talk behind your back - and only the good stuff!
A shower of good feedback
Form groups of 3. Each group arranges their chairs so that 2 chairs face each other and the third one has its back turned, like this: >^<. The two people in the chairs that face each other talk about the third person for 2 minutes. They may only say positive things and nothing that was said may be reduced in meaning by anything said afterwards.
Hold 3 rounds so that everyone sits in the shower seat once.
