Two families come together for Thanksgiving after meeting through wrong number

Phoenix teenager Jamal Hinton was in class at Desert Vista High School when he got the following message from an unknown number: "Thanksgiving dinner is at my house on Nov 24 at 3pm. Let me know if you’re coming. Hope to see you all. Of course that includes Amanda & Justin."
Intriqued by the message, Jamal replied to the message enquiring who it was, only to get the reply: "Your grandma."
