Service - Kindergarten

Some time ago I have started a voluntary service in the local kindergarten. It is the kindergarten I used to attend when I was a child. It is really nice to go back there not as a student but look at everything with the teacher's point of view. When I went there for the first time I was afraid and didn't know what should I do to not break any rules which are set there. I didn't know how to act towards children. I might say that I was more stressed than those children when seeing the unfamiliar person. 
My first task to do was to help in decorating the hall for the masked ball. I saw that being the teacher in the kindergarten not only means to teach children but also have different work such as hang the string right under the ceiling. 
What intrigue me is that in every group, independently of age, there are same people such as leaders or the outsiders. You can watch their behavior and make some conclusion. By now I had my service in the two groups - in 4  and 6 ages group. The interesting and quirky fact is that in those two groups I immediately focused my attention on children who are somehow different, who are unique. They diverge form others. It is really strange but I feel bonded with them.
