Stranger added to family group chat restores 'faith in humanity'

Like any good great-grandmother, when Beverly Garrett was awaiting news on the birth of her great-granddaughter, she reached out to all the phone numbers she had for her grandson -- even a number that no longer belonged to him.

As Zach Garrett waited for his wife Sierra to deliver their daughter, Layla, he responded with updates to his grandma's group text. What came next gave Garrett "faith in humanity," he told "Good Morning America."

"My grandmother was trying to get a hold of me for updates, and she accidentally added my old cell phone number and my current number," he said. "When we first heard from him I was a little embarrassed that me and my grandmother were talking away with him stuck in our group chat, but his selfie brought so much humor to the situation. We all had a good laugh! Bobby could have been really rude or told us to take him out of our chat but he didn’t. He was so nice about it."
