Karen & Family: So very sorry to hear about Ms. Grace. She was the sweetest person! I remember her well when she worked at Beall's (or Stage). Always so pleasant and friendly! She was the one "salesperson" I actually looked forward to seeing when I went shopping. Prayers for your family.

I spent almost every summer and every holiday with her growing up. Her and my grandfather would drive from new Iberia all the way to Dallas every summer and every holiday to come pick me up. She had the best coffee milk, you can ask my cousins we gulped that down. I have to say I had a wonderful childhood growing up with her. Wake me up almost every morning with either blueberry muffins or donuts or a half pound of bacon. I’m going to miss her dearly but I know she’s going to be taken care of by Meme and my dad.
