I'm certainly not going to defend Ashley, as I do think she's a very spoiled and immature girl.
However, she did indicate that her mom has teased her before about that very same thing. I don't think Jacqueline is delibeartely mean, but I do think she's totally passive aggressive.
And, people can make teasing comments for a long time. That doesn't mean they're correct or OK. Ashley said her mom had said that before and she knew it upset Ashley.
I've seen that sort of thing happen far too often in families. It's not right.
