Got the taste of your lips on my mouth still hangin'
When you kissed me right back
I called you up on the phone but you're still not answering
Will you hit me right back?
Rainy Saturday night with my shirt you're wearin'
Would you give it right back?
Now i'm callin' you out cos you left me hangin'
Would you hit me right back?
Baby, oh, where'd you go?
Why'd you leave me hangin'?
Can't get you off my mind
Know that i'm always waitin'
Could be the one for you
Why do we keep denyin'?
Would give it all for you
Call me and i'll come runnin'
And when you finally decide to pick up my calls
Why you did me like that?
If you push me away baby know that i'll still
Will be running right back
When you tell me your heart still belongs to someone
Baby I can't take that
But let me know if it ends baby i'll be waitin'
Girl you know me like that
