Of course it depends on the image of the person they had created before my eyes or mind. If someone I don’t like approaches me, I’d just ignore them and in worse cases, if I’m angry, they will see the super sarcastic version of me and I swear I pull their soul out of their mouth.
On the other hand, if someone i like approaches me, I behave normally around them. Even I curse my besties a lot. Not to insult them, but because I feel at ease around them
