Overheard in the van this morning:
Oldest Son (5): Abba [Hebrew for Dad], why did G-d choose the best rabbi for us?
Abba: G-d may have helped him decide to become a rabbi, but the congregation decided they wanted him to become our rabbi.
Oldest Son: Oh. So G-d didn't say, "Hey, do you want to be a rabbi?"
Hmm... how to explain the concept of free will and career choices to a 5-year-old...
