Physical contact and greetings

I noticed that the people of Sevilla, I don't want to generalize and say Spain, are much more comfortable with physical contact. People are okay with speaking to you at a much closer distance than back at home and standing closer to you in waiting lines. It always kind of throws me off to be honest. It is something I definitely have to get used to. While talking to you, whether it is a man or a woman, expect a hand to slide across your shoulder or your lap or even just around your shoulders. But I personally like the way they hello to each other with a kiss on each cheek.
Another thing I noticed just standing by waiting for a taxi is that when they say hello and ask each other how they are, the other person will stop and actually tell the other person how they are. Usually back home we ask how are you and we just say it to be friendly. I know we all know this because the other person never actually stops and says how they are, they just say hello and keep walking or they say they're okay. It is always a short answer.
