(17 yr old daughter on phone to Grandmother with me in same room.)
Daughter: Nana, do you have any AAA Batteries?
Me (yelling to be heard on phone): It's for her vibrator!
Nana (which daughter repeats to me): You need D size.
Me (which daughter repeats over phone): Speaking from experience?
Daughter: Ewww, must be true, Nana isn't saying anything!
