When I traveled to France, I was so surprised that people gave each other two kisses on the cheek when they met. Here in Peru, we give only one. Two kisses seem like too much haha. I think I never got used to the greetings because I stopped at one kiss and people stared like saying "why isn't she giving two kisses?".
Also, as a 'latina', I noticed the coldness between people. Young people didn't spend much time with their families, they just went out with their friends. I think here family time is more valuable and teens get out of their house later in age. Just to point out this is not a generalization, there are probably families that aren't like that.
I of course would go back to France, I love discovering cultural differences because that shows me how rich this world is!
