Grandmas are incredible. They're loving, and their food is amazing. So when grandma asks you over to Thanksgiving dinner, of course you say yes. But, what if sweet grandma sends the message to the wrong person?

One Mesa woman thought she was texting her grandson and his girlfriend. She texted her grandson telling him dinner would be at her house at 3 p.m. this year. She wanted to make sure his girlfriend would also be coming.

But on the other end of the text conversation was not the woman's grandson, but a 17-year-old senior at Desert Vista High School.

Jamal Hinton said he was sitting in class when he got a random message in a group chat.

He texted the woman back asking who it was, and the woman responded with: "It's your grandma."

Hinton said he figured his grandmother had gotten a new number, so he asked for her picture "just to double check."

And the woman responded with a picture of herself.

He then sent her a picture of himself to establish that they were not related, but figured he'd ask her if the offer for Thanksgiving dinner still stood.

The woman, a complete stranger, said she would save a plate for him because "that's what grandmas do....feed everyone."

Since then, people have gotten in touch with the woman asking her for a plate too. The woman has since changed her number, but her grandson has kept in touch with Hinton, even giving him her new number. Hinton said the grandma's family told him they'd send him the address and have a plate ready for him.

"I thought, 'Wow, this lady is really nice,'" he said. "Any other person would probably blow me off, and be like, 'No, never text my number again,' but she was actually pretty nice and sweet about it."

He said he knows "there really are still nice people out in the world."

So, next time a stranger texts you, will you respond? It could be grandma...
