This morning at breakfast....
Me: that's a third of an hour
David: what's a third?
Me: (launching into an explanation of fractions, working my way through thirds and getting back to "half")....if I have this piece of cheese here and I break it in two pieces and I give you this one, what's that called?
Yep, that's right.
P.S. Mensch is the Yiddish word that is used to describe a good person.
P.P.S. Immediately after, Sam pipes up: I want some cheese too! LOL.
