She spent the night out being rude to your friends and family. Disinterested, on her phone. Just talking about herself all night, thinking the whole world was about her. Not asking anyone else about themselves.
Now they will all think she’s stuck up. First thing’s first, take her home, strip her completely and deliver a lesson for acting in such a way. You know she’s sweet really. Maybe it’s a shell when she’s not comfortable in a social situation? But she will never, never act like that again.
If she wants to try and be so high and mighty on another night out warn her you will deliver this to her in the bathroom of the restaurant, exactly like this. And she can explain to the table why her make up is running all over the place and why she has tearful eyes.
