C When I opened the door and saw C You smiling once again I felt so lucky F And so warm inside; C Opened the door and saw C You smiling even though The snow was blowing F It's so warm inside [Bridge] Em Hey, I think I'm falling in love Dm7 Dm I guess you didn't know Em Hey, I think I'm losing my cool Dm In case it didn't show [Chorus] Am But a habit of you F Would be hard to give up Am A habit of you F Would be hard to give up Am Yes, a habit of you F A habit of you could be hard to give up {Verse 2] C When I opened the box and saw C My orange birthday cake I felt like crying F That's all I could do C When I opened the box and saw C My orange birthday cake That's all that's left of F Mama's birthday boy [Bridge] Em Hey, I think I'm falling in love Dm Em Dm7 I guess you didn't know [Chorus] Am But a habit of you F Would be hard to give up Am A habit of you F Would be hard to give up Am Yes, a habit of you F A habit of you could be hard to give up [Verse 3] C When I opened the door and saw C (Uh oh) C You smiling back at me I felt like crying F That's all I could do C When I opened the door and saw C You smiling back at me That's all that's left of F Mama's birthday boy [Bridge] Em Hey, I think I'm falling in love Dm I guess you didn't know Em Hey, I think I'm losing my cool Dm In case it didn't show [Chorus] Am Cause a habit of you F Is hard to give up Am Cause a habit of you F Is hard to give up Am Cause a habit of you F Am F Am F Am F A habit of you can be hard to give up
