When I told my friends that I had plans to take (my then) thirteen year old stepson to Paris - they took bets.  One pal planned to have a t-shirt printed for me that said: 'Oo-la-la.  I took a thirteen year old to Paris and survived.'  In fact, some of the trip was challenging.  But thirteen year olds are going to roll their eyes whether you're in the grocery store or in the Louvre.  I'll choose the Louvre over the frozen-foods aisle any day.
