I went on a trip to italy like that. There was a very nice jewish family from canada that was full blown socialist, a mother and daughter from california that got wet at the thought of being "revolutionaries", and an old woman from new york that was liberal as hell, but seemed to not really like black folks. There were conservatives as well that balanced it out, but the conservatives, as you would expect didn't voice their opinions at every turn.
The mother/daughter team was constantly talking about "changing" every fucking thing that you can think of. It got old as hell. Finally, one woman asked the mother what she did as far as work and proceeded to give her a lesson on how the real world works and what really happens out there. It was funny, but I'm sure it went in one ear and out the other.
