My Daughter Doesn't Trust Skinny Grandmas

My mom relayed a conversation between her and my 11 year old from yesterday that made me laugh:

My mom:
"I am not liking these photos of me. I look too heavy. I need to lose
some weight before David and Nancy's wedding (my brother and his fiancé)"

My child:
"I think you look good Grandma."

My mom:
"Thanks I appreciate you saying so but..."

My child:
"No really Grandma. I think grandmas should be a little bit chubby. To
tell you the truth I don't really trust skinny grandmas."
