pea in a pod

Michelle's mom came for a visit for a week. Its hard to summarize a week with Michelle and her mom. But I'm going to try. Here is a snippet of a conversation that could give you a glimpse into the wacky world i lived in:

Michelle's Mom: "What will the weather be today? should i carry a sweater?"
Michelle: "Twitter stock opened at 45!"
Michelle's mom: "45? I'll definitely need a sweater."

which leaves me dazed and confused.
