Im curious as to whether friends of the opposite sex are allowed to kiss each other on the cheek. One of my friends thinks that it's usually the girl that does it to the guy so it's ok. One of my friends says it means they like you and have feelings for you. This friend also says it depends on the situation. Did it happen when you greet or say good bye to each other? Or out of the blue? Have you been friends for a long time or recently met them?
Isn't there some societal norm about being friends with the opposite sex and what you're allowed or not allowed to do?
