women from Tucson and a couple from Berlin

We live in a house that rents out rooms. Tonight we have two mom types women from Tucson and a couple from Berlin doing the "employees with benefits" thing having a working vacation in the USA.
The Moms couldn't wait to hit the nightlife once their friend's wedding concluded. The Germans were perplexed with the Ptown culture and spent most of the week in their room. Lots of grinning people engaging in half conversations with them all day freaked them out. "Germans don't normally share greetings and philosophical observations with strangers" I told them to act like the whole city is a huge cocktail party. I told them it's ok to go out there and be friendly. "No such thing as friendly, in Germany it's called "smiling with no reason". The Moms are a riot. I can't wait to find out what they got into.
