Guitar Lyrics

I kept looking, but I couldn??t find the chorus of the song anywhere so I tabbed it by ear along with the rest of it, I played it along with the song and it sounds at least 98% accurate, I love this song, enjoy!
Chords:
I'm sitting by the window of your thirty-second floor apartment
Waiting for your phone calls all to end
I'm sitting watching wind blow, watching time go, watching cars go by
I'm waiting for these memories to begin
(riff 1)
If I threw my guitar
(riff 2)
Out the window, so far down
(riff 3)
Would I start to regret it
Or would I smile and watch it slowly fall?
(play this during chorus)
(riff 1)
(riff 2)
(riff 3)
you??ll probably have to listen to the song a few times to get where this part starts and what not but when you get the hang of it, it??s very solid. i haven't quite figured out the part after the chorus, but if i do, i'll be sure to post it =). keep in mind this is my first tab so any suggestions or corrections are totally welcome, have fun, it??s a great song.
