Paper Bag lyrics

I'm like a paper cup with a pin prick
You can fill me up;
I'll only stay full for a while
And wisdom's only shown me
That my loneliness is all my fault
It's all my fault
I don't know what I have done wrong

(Chorus)
You say you understand me
Well I don't get you at all
It seems everyone around me
Is so good at faking it
That I don't know
Just how to act around you
[ Lyrics from: http://www.lyricsmode.com/lyrics/d/dear_and_the_headlights/paper_bag.html ]
I'm like a paper bag, but the bottom's wet
It must be something bleeding internally inside
I didn't know the things that you never
Did can stay with you your whole life
And I don't know what I have done wrong

(Chorus)
You say you understand me
Well I don't get you at all
It seems everyone around me
Is so good at faking it
That I don't know
Just how to act around you
How to act about you

I've got a memory but
I can't hear what you're saying
You're looking straight at me
But I'm looking the other way
