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
