We have been discussing big life lessons at our house lately.
We got told the other day that Linnea had not been very nice to a few of her friends at school and were asked to talk to her about it (although the teacher thought it might be down to "end-of-term-itis"...) - and it so happens that the same day we were also told she had been pushed into a door by another kid at school, and she came home with a big graze down her back.
Nathan tried to tell her that maybe it was karma? Maybe because she hadn't been nice to someone it all went around and someone else was then not nice to her... Linnea didn't quite grasp the concept of 'what goes around comes around' though - maybe trying to teach a 6-year old about karma is a little bit early? :)
