Thinking of you... (Music video)

I am really into this song, I find it very sad, beautiful, and Katy's voice is great... Haunted by this song today... I keep repeating her song, and I cry too...

Comparisons are easily done
Once you've had a taste of perfection
Like an apple hanging from a tree
I picked the ripest one, I still got the seed

You said move on, where do I go?
I guess second best is all I will know

You're like an Indian summer in the middle of winter
Like a hard candy with a surprise center
How do I get better once I've had the best?
You said there's tons of fish in the water, so the waters I will test

He kissed my lips, I taste your mouth
He pulled me in, I was disgusted with myself

You're the best, and yes, I do regret
How I could let myself let you go
Now, now the lesson's learned
I touched it, I was burned
I think you should know!

'Cause when I'm with him I am thinking of you
Thinking of you, what you would do
If you were the one who was spending the night
I wish that I was looking into your eyes

Won't you walk through?
And bust in the door and take me away?
No more mistakes, i promise
'Cause in your eyes I'd like to stay..
