To help me with this task, I read Madonna's Mr. Peabody's Apples to him. (I'm sure there are lots of other books out there (perhaps better ones) about the subject but this is what was in our at-home library).
This particular book is about the consequences of spreading rumors. The book also talks about thinking twice before judging others.
We discussed that once words are spoken or written, they can never be taken back and some times feelings can be hurt.
Therefore, we must always choose our words wisely and kindly.
A great lesson for little ones and grown ups alike.
Happy weekend to all!
