Cheek kissing: a cultural practice.
The first time I met some people here in Canada I came up to them and kissed both of their cheeks, sometimes I felt that they were a litte surprised because It seemed to them that I have had invaded their personal space. I explained to them that it is a way of greeting and expressing friendship. That is a European tradition (in some areas). Here greeting people with a warm handshake is both friendly and polite.
How would you feel if someone you don’t know hugs you and kisses yours cheeks?
