Sometimes, the smallest gestures can make some of the biggest impacts -- especially in the lives of children.

On Monday, Mesa police shared the story of 90-year-old Betty Draper on Facebook.

According to the post, Betty decided about six months ago she would start collecting baby dolls from Goodwill stores. From there, she spent hours refurbishing the dolls. She'd untangle the dolls' hair and wash them. She even made new clothes for them.

Mesa police said Betty donated her first batch of 12 dolls at the beginning of summer to the Mesa Family Advocacy Center. There were to be given to victims of child physical and sexual abuse.

"This first batch did not stay on our shelves long at all," Mesa police wrote.

She was back just last week with a whole new batch.

"Your love is felt and shared," the department wrote.
