My mother was not very demonstrative with her affections when I was growing up, she did love me but didn't go into open displays of it so I hadn't been used to being hugged or kissed on the cheek by anyone not even family. Being painfully shy I just couldn't greet anyone like that either but now grown up having travelled a bit more and meeting people from all areas I tend to go with the affectionate greetings because it is mostly followed by a smile. So much better.
