O gosh, the 3 or 2 kisses is always so embarrassing! When I just moved to Paris I was so used to giving 3 kisses, it always ended in an uncomfortable situation where I was reaching to one's cheek to give another kiss, while the other one didn't...
I adapted fast
A good thing though I learned there, is greeting people of my age (friends from friends) with a kiss (or 2 in fact) on the cheeks. It gives an immediate friendly feeling. I wish we would do that in Holland too, sometimes I do but it's not common.
I have to say 3 kisses is a lot! Really have no idea where that comes from...
With friends I see frequently, we always kiss once. It saves time

haha no, I think that means here you see each other very often =)
