Move Faster Pigeons

Azadeh is anxiously waiting for the time when she can go to school and play with the other children. Her father says that soon she can go, when the clock strikes seven. It seems to Azadeh that the two pigeons in the clock make the hands move by pulling on the bar they're connected to. The pigeons look tired, but Azadeh wishes for the pigeons to move faster so she can go to school. She discovers that one of the pigeons has a broken wing and it cannot work properly.
