This is from my dad (Ellen’s sleeping over there for a few days):

Sitting at starbucks. I say to ellen,
“if we count we usually count starting with 1.”
She: right.
me: then what is the point of zero?
she: how else can we understand 4 minus 4, or 10 minus 10.
I just nodded sagely, sipped my water and ate some more cookie.
