My first teaching experince with children

I have just finished work today. And it has been a long day indeed. This is my second day working with children at school. I teach English in 1st and 2nd grade. I really love working with them because they are sweet and kind. They are very friendly. But sometimes they behave so badly that you want to run away inmediately.
Personally speaking, I beleive that this age is the best period in any individual`s life. And I would really want to go back at this point again. It happens to me that when I see them play I want to be part of their games. Sometimes I do play. And I feel a child again.
As a teacher, I think that working with children is a great challenge because you have to learn to draw, to sing and so many other things that you do not imagine. When you see that the children are engage in the game or they enjoy the activities you present them you feel happy.
On the other hand, there are times when they misbehave all the time. They speak to you all tagether. They want you to correct every single thing they do. Anyway, I think I will need to be more patient with them. I hope I can because sometimes I feel that tolerance will not last long.
