Knock knock knock who's therewho's Knock knock knock who's thereanybody Knock knock knock who's therewho's Who's therewho's therewho's therewho's there [Chorus:] If you're wondering while you're knocking Why I ain't opening up I'm loving your best friend If you're wondering while you're knocking Why I ain't opening up I'm loving your best friend If you wonder why I'm tripping Started out when we stopped talking Found myself in the corner off drinking But the problem just won't go I distract myself with music But my ear drums just refused it So I dig into my wallet And I stare at your photo When I think of all the time Candlelight, dinner and wine You're the rib that's in my spine But you would not make no time So your girlfriend came around All those times that you left town Made me feel just like a king When she sat down on my crown [Chorus] Now it might seem kind of shady And it shoots like a 380 Though I'm in another lady I'm still thinking 'bout my baby All the things we used to do, when I used to call you Boo It felt like we were in grade school But all those days are through All those thoughts of going to the chapel It's like someone just burned my castle Paint the picture like Picasso But the image fades Now for some it might sound deep But I just received a beep So I called back anxiously She put her lover on the line If you're wondering when you're calling Why I ain't calling you back She said I'm loving a new man (she said to me) If you're wondering when you're calling Why I ain't calling you back She said I'm lovin' a new man (She said that she had someone new) If you're wondering when you're calling why I ain't calling you back I'm loving a new man Oohh oohhbaby please (baby please) You know this situation's buggin' me (buggin' me) You got someone else but your girl's with me (girl's with me) It's only so I can get by [Chorus]
