This conversation took place in the car. Of course.

Look! I can drive, say cheese, and take a photo of all three of us at the same time! *Smile* Actually, we haven't even pulled away from the house yet.
Mgazi: How old do I have to be to chew gum?
Me: Thirteen
Mgazi: Awwwww. Why thirteen?
Me: Because I said thirteen and it sounds like a nice number. Would you prefer fourteen?
Zaffy: I want fifteen!
Me: Deal.
Mgazi: Yay! We can chew gum when we’re fifteen!
[48 seconds of silence. I know this because silence is such a precious commodity in our car that I have taken to subconsciously tracking how much of it I experience during any given ride. Let me tell you, it's not much.]
Mgazi: How old do I have to be to drink wine?
Me: Twenty-one.
Mgazi: Why twenty-one?
Me: Because twenty-one is the legal drinking age. If you drink any kind of alcohol before you are twenty-one, you are breaking the law. This will make the police officers mad. This will make your mommy mad.
Mgazi: How old do I have to be to drink soda?
Me: Twenty-one.
Mgazi: Why twenty-one?
Me: Because soda is bad for you. It’s only good when mixed with alcohol.
Heehee! I love your mommy vignettes.
Awww. Warm fuzzy.
