Mom Drives ME Crazy

Mom: (sharp intake of breath)
Me: That scares me to death!

Me: Can you not frown?

Mom: (silently gripping door handle tight)
Me: Wow, your knuckles are white!

Mom: I'll drive home from here.
Me: But you have nothing to fear!

Mom: (heavy sigh) Fine, I'll try to stay calm.
Me: Thanks? (I hope I survive driving with Mom)
