Salam, I have quite a few female class mates who joke around with me. I have set a firm boundary of no physical contact but I still feel guilty as I normalised this when I reciprocated (I even find myself starting the jokes regularly) I don’t know what to do even if I stop from my end I’ve normalised it for so long I know they won’t, in this case can I laugh at their jokes? I don’t want to be rude and living in the west this sort of banter is normalised and is considered small talk.
