Always be ready to give an account

I was at Church today and three people asked me how law school was going and what year I was in (again) and proceeded to congratulate me with expressions such as "You're going to be a lawyer!" "What kind of law do you want to practice?" "You must be very proud to have almost completed it."

I don't know where to begin. Do I say that I never really wanted to practice law (at least not very badly) and that I now haven't the foggiest idea why I even went to law school in the first place? Do I say that if I never practiced a day and never took the bar, I'd be happier than they could ever understand?—like the happiness one feels when one at long last finds a door surmounted by the legend, "Gentlemen"?
