Greetings in the 3 continents I've been to in the past 2 weeks...

In North America it's wired for some people that Iranian guys kiss (on the chick) when greeting... They says it's "gay" and whatever... But when I was in Austria I realized they do the same thing people do in Iran. In both places people just use the lips to make a kissing sound and I don't see what the big deal is in NA.
