the school cleaning lady

This lady is always hanging around the school with 2 small kids, and finally I asked what was up with that. (the girl in the red shirt and then a boy, not pictured, about a year older). I guess she does some cleaning during the school day and then sweeps the floors after we have all left. She is really nice, but wouldn't look at the camera for a picture. This was the day that we had cake at school to celebrate Christmas, so thats what they all have in hand.
