For this game, you need paper and pencil for each participant, plus a hat or tin.
The game is played in a circle.

Ask everyone, including the moderator, to complete this sentence on paper (anonymously):
“In this trip/group/program, I am afraid that …“
Put the scraps of paper in the tin, or receptacle, in the center.

Pass the tin around, stopping at each person while s/he draws one out and reads it, enlarging on the sentence and trying to express what s/he believes the writer was feeling. Explain that there are to be no comments about what will be said.
The moderator goes first!
(For example, the group leader reads the first one, and might say:
“In this group I am afraid that I will be laughed at … (continues talking) - I am afraid to express my feelings because everyone laughs at me, so I never say anything.”)

Continue around the circle.
The leader should make sure that everyone just listens, and does not comment, or argue.
Then discuss what was noticed or discovered.

Variations:
Likes and dislikes in a hat (two tins)
Worries in a hat
Gripes in a hat
Wishes in a hat, etc.
