I don't know her - A mean way of saying she’s not worth your time and never was

A mean way of saying she’s not worth your time and never was. She’s a nobody and you’re not even pretending to care.

I don’t know her. She’s the reason I don’t like strangers.

I don’t know her. She’s like that weird kid who sits alone at lunch.

I don’t know her. She's the extra cupcake no one wants.
