I know this girl, she's always on my mind   She lives in her world and I live in mine   I should forget about her and I've tried, oh Lord knows I've tried   But I want to know her, and here's the other side      I've got someone waiting for me every night   She's the only one I've ever loved, it's been that way for the longest time   And she's the one that makes my world go right   And it tears me in two because I know where I'll be tonight      I think she knows it   I think she knows      I live in two different worlds, two different worlds   One that belongs to me, one could be wrong for me   Two different worlds, two different worlds   Ohh, it's two different worlds      Is she that different or is it the thrill of someone new?   Strung out on her, I need her love, I need it bad, that I know, I know it's true   I'm the one that lies awake alone   And I know, she's the one that makes me stray from home      And I know it   Yeah, I know it      I live in two different worlds, two different worlds   One that I may regret, one that I can't forget   Two different worlds, two different worlds   Ohh, it's two different worlds      No, I can't explain this emptiness   No, I know that I can't go on like this   Two different worlds, two different worlds      Ohh, it's two different worlds, I live in two different worlds   One that I may regret, and one that I won't forget   Two different worlds, but I can't live in both, I know   One world I must let go
