Left your heart by the front door baby You don't need to come round ma way no more That's what ma girlfriend said to me at 10.23 on a lonely mondaymorn' Found another and he treats me good like you never could Go away i think you should. Needed you, but you weren't there so now i don't care that sheput her finger in the air. CHORUS Baby how can you doubt my love when you're the reason I'msmiling (Cuz baby love you're the reason why) If you deny my heart, then you should know that it's for you thatit's sinkin' (Cuz everything I'll ever need is you) Na na na na naa, I'm gonna lose ma mind Na na na na naa, You are the reason why Yesterday I saw ma ex-girl at the mall With some kid by the name of Tommy Smith She was on his stick and in the corner of her eye she saw mestaring at her and him She kissed him then she smiled at me they both started laughingthen they walked past me She was lookin at him how she looked at me right before we'd gohome and do our thing I said "Gimme one more chance, I love you. Gimme another chance I can't live life without you" She said "Get away from me boy I don't care" walked away with onefinger in the air CHORUS Baby how can you doubt my love when you're the reason I'msmiling (Cuz baby love you're the reason why) If you deny my heart, then you should know that it's for you thatit's sinkin' (Cuz everything I'll ever need is you) Called her up on the telephone, ma Casio read 2a.m. Moonlight shone through ma window had a song by Hendrix in mahead Never understood this girl, this thing called love or the worldwill end Let it ring two more times she wasn't there Na na na na naa, I'm gonna lose ma mind. Na na na na naa, You are the reason why. (you are the reason why, why) Chorus
