Parenting is like a balloon

Somedays I feel like parenting is like being an inflated balloon that someone hasn't tied. You are all good and full of patience, then all of a sudden there is a massive release... you bounce wildly around the room, making hissing sounds - then you are deflated, spent, and at wits end. And you wonder what happened, for just a moment ago, life was good and full. Yup... you reconnected with the kids at the end of the day.
