Sorry About Dresden - Butterflies lyrics

I spied a green light from my roommate's view, So little light in wintertime. I crossed the street that you crossed too, But I still won't cross the line. It's not as easy as it seems, To do what you think is right. Am I still in your dreams, Or was it just that night? I searched my room for a souvenir; So little of you I posses. Did not know how to take your remarks, But I took them none the less. It's not as easy as it seems. There's nothing with you in the dark, Am I still in your dreams or was it just a lark? I haven't seen you in a week or two, I've used caffeine as a crutch. You gave me an invitation once. What gives you bu*terflies don't give you much. What gives you bu*terflies?
