Hardest Part

I wish I knew how to feel right now
Wish I knew what to say
But, every once in a while I wonder
If I subconsciously pushed you away
I put my feelings in empty bottles
Is that the wrong thing to say?
Your new love makes my
Heart feel hollow, hollow, hollow

But, the hardest part is that I
Feel like I never knew ya
The hardest part is that I
Still can't forget about ya
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day

Where was I for your transformation?
No more spark in your eyes
I don't want any information
But, I can't help but wonder why, oh oh
(La la aye)
I can't stand it when our song comes on
(La la aye)
Though it used to be my favorite one (Uh)
Don't you know you make my
Heart feel hollow, hollow, hollow

But, the hardest part is that I
Feel like I never knew ya (La la la)
The hardest part is that I
Still can't forget about ya
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day
Your echo goes dum da-de dum do do day

Oh, somehow you left me empty
Oh, you're still there in the dark
To think that I never knew ya
Oh, that is the hardest part
Oh, somehow you left me empty
Oh, you're still there in the dark
No, I can't forget about it
And that is the hardest part, oh

But, the hardest part is that I
Feel like I never knew ya (La la la)
The hardest part is that I
Still can't forget about ya
Your echo goes dum da-de dum do do day
(You echo on, you echo on)
Your echo goes dum da-de dum do do day
(You echo on, you echo on)
Your echo goes dum da-de dum do do day
(You echo on, you echo on)
Your echo goes dum da-de dum do do day
(You echo on, you echo on)

Dum da-de dum do do day
Dum da-de dum do do day
