So if I'm having a conversation, and the other person is wiping their nose a lot, does that mean they think THEIR nose is dirty, or that they're trying to tell me MY nose is dirty?
My "wiping nose because its dirty" is very different to my "pantomime wiping nose to indicate someone else's is dirty". Also, I will say something before for the latter case like "Hey, you have a little bit of..."
Idk if it's how I was raised or smth. But I don't get how can that come off as offensive (or similar) in any way.
A: "Oh hey you got a little choc on the side of your mouth"
B: "Fuck you, how dare you? I hate you now. Do not ever talk to me again"
I just simply don't see this happening, ever. If it's a stranger and you start the convo with this then you might not be on good terms, caz it's super wierd. But to a friend, lover, colleague, boss, manager I only see an outcome where they thank you, or worst case just turn away, act shy and clean it off.
Anyways. This wasn't what you were asking. If they are scratching their nose, just let them(?). Like what harm does it cause you? Maybe they are sick, allegic, or feel dirty or itchy, it's probly best to act like you didn't even notice it :/
