Your 4 year old is eating a watermelon wedge.

She loves it.

And you love watching her bite diligently closer and closer to the rind.

You turn away to talk to your spouse.

You turn back and there is no more watermelon. No red part. No rind.

Behind the empty plate on the table is nothing but your little girl wearing the satisfied expression that only comes from a job well done.

That is bliss.
