I could have
I might have
I thought...
what do I know?
[ Lyrics from: http://www.lyricsfreak.com/b/ben+folds/still+in+love_20704974.html ]
but for a moment,
there was a minute
I thought just for a second
maybe... it... was...

could have been
might have been
I thought for a moment it

too bad,
sorry about that

could have been
might have been
feel bad about that
