A school anecdote

Well, today I will tell you about a school anecdote, tells you something is difficult to me because I don't remember many things I did in the school, because I have bad memory for this type of things.
But I remember one anecdote because I remember the photograph after the moment jajaja
When I was study, maybe second grade of secondary, I participated in the instrumental group of school, the name group is "Mosaico" (anyone understand why this name because the teacher chose that), well this group include seven person, each one of them have different personality and for this reasons us complement so good. Well, I continued whit the story, we played in many different events school, all the time we lose classes because we need practice the scores before  the concert. Many times we stayed in school until the night  because the events was in this time. One of this time, we played in the award ceremony for the students of different area, for example: basketball, volley, exchange students. The point is that we were never rewarded for anythings, even though we represented the school in different competition or played in all events. Then one of the girls of the group and me , before going out to played, we went to the place when teachers stay and we started to annoy him for a long long time (all group annoy him) because never us reward jajaja. The teachers only saw us and laugh. Before we played, started the premier, we talk between us and said the teacher is bad (no seriously) for the same reasons mentioned before, in this moment we hear the name of the group followed by the name of each one, we are surprised and started laugh strong, we go to received the diploma laughing and the whole school looked at us weird. After the teacher say us: See how they speck ill of me and I had this surprise and continue laugh with us.
