Ask each team member to briefly describe how their right neighbour felt during the iteration. Their neighbour confirms or corrects the guess. Once all participants shared their best guess about how their teammates felt, you get an idea of how connected they are, how communication is flowing in your team and if people are aware of the feelings expressed, in some way, by others.
Thinking back about the discussions, everybody writes a reminder for her- or himself about a change in their own behaviour they want to try during the next iteration. It's for quiet self reflection and is not shared with the group. They take their respective sticky notes with them to their desktop and put it in a place they will look at often.
