That's why!

If you ever wonder why puddles exist, here is the reason why: JOY!
Joy, for kids and dogs (and grown-ups, if they still know to behave like children).
And of course for all kinds of animals to drink.

We had a lot of rain, some with thunder and lightning. The rain was so heavy shortly before I reached home, that D. picked me and Caspar up with her car. (Of course it was dry again when we arrived...)
