Behind-the-scenes

This evening was the Christmas event at the youth center of my children.

It is difficult to take pictures in this environment by a combination of lack of ambient light with high intensity lights on the subject. However, some photos went right in the experience.

Here we see a group of 12 years old children singing carols(one of my sons is in the group), while the monitor observes nervous from behind the scene.
He had reason to be nervous. They weren't the best singers
