After the divorce, her teenage daughter became increasingly rebellious.

It culminated late one night when the police called to tell her that she had to come to the police station to pick up her daughter, who was arrested for drunk driving.

They didn't speak until the next afternoon.

Mom broke the tension by giving her daughter a small gift-wrapped box.

Her daughter nonchalantly opened it and found a small piece of a rock.

She rolled her eyes and said, "Cute Mom, what's this for?"

"Here's the card," Mom said.

Her daughter took the card out of the envelope and read it. Tears started to trickle down her cheeks.

She got up and gave her mom a big hug as the card fell to the floor.

On the card were these words:

"This rock is more than 200 million years old. That's how long it will take before I give up on you."
