A father and his teenage daughter were going out in the car when the daughter started a conversation:
Lauren: Dad, do you know what the most commonly used letter in a girl’s name is?
Me: Hmm, is it a consonant or a vowel? (Silence.) Please tell me you know what consonants and vowels are.
Lauren: You’re no fun, Dad. Forget it.
Me: What is a vowel?
Lauren: OK, OK. A vowel is … ahh … eh … well, oh … uh …
Me: Close enough.
