I met a lot of people during my nine months stay in CAL. I found them refreshingly happy to contact strangers (in this case, me). I was asked if I want to have a lift with the car with my grocery bags and I was so delighted by this unusual offer that I immediately said "yes". You wouldn't get this offer standing in line in a German supermarket.
That would be the other side of the spectrum as the woman who took me to my friends house was not up for a punch line.

Americans are know for their aggressiveness and of course, that cannot be said about all of you. This can be potentially bothersome as well as potentially inspiring.

People made vacations in Thailand in order to get laid. But I would say that it was much easier to do that in the States. HaHa!! At least, for me as a female.

The aggressiveness, on the other hand, can be a bit scary if you are not used to it.

Here, in my country, police officers never wanted to educate us (this may have changed in the meantime). One time I was giving a safe trip home from police who drove behind me in order to accompany me because two of my back lights got broken during my journey. They escorted me 25 Kilometers until I arrived safe at my moms house. They easily could have lectured me and ordered to park the car and could have given a damn of how I managed to get home. But they decided otherwise.
