my family is european, from most of every country in europe and some of them kiss realitives on the mouth, side of the mouth, or the cheek, along with hugs. others do the air cheek kiss. Ive had one kiss me full on the mouth, but it was closed lipped, i thought it was weird too.
he explained thats how he was taught to do it as most do where he was born. Ive since learned many other cultures do something like it or close to it, which is about affection, and love of family. nothing other than that.
though i will say there are a lot of perverts out there still, and you never really know about it. Its usually people you dont expect either. So you never really know if their doing it from affection, or other reasons, so i dont judge people since i dont know what their thinking.
