This morning when Joseph and I were walking to school, one of those fat ducks by the wilk waddled past us. Of course I wanted to chase it, but Joseph said, "No. It probably has enough stress in its life." - To which I said, "Wow!! What a kind thought. I never thought of it that way!" So, we didn't chase it.
Moral of the story: Be kind to others (yes, even ducks). You don't know what they're going through.
