You Don't Know Me

She's got a boyfriend all of a sudden
 She's never had one before
 She's looking for the thumbs up when they're walking through the door
 She's showing him off by making him talk
 She's putting her hand in his pocket
 It shows on her face, what she doesn't say
 What she doesn't say
 You don't know me
 You don't know me at all
 She doesn't know that we know
 That we've been there before
 We always pay attention when she walks through the door
 It's the clothes that she chooses
 It's the words that she uses
 She says, "You don't know me
 You don't know me at all"
 She's trying hard to pretend that it's not really happening
 But we can see her smiling from afar
 We don't see her much anymore
 But we can hear her whistling as she walks to her car
 You don't know me
 You don't know me at all
