A                     D        A
It seems like only yesterday
               D A D A D E
I didn't have a clue
                                        D  A
I stood alone not knowing where to turn
                     D    A
Now suddenly I look around
                 D A D A D E
And everything looks new
                                              D    A
I don't know why, but I think I'm starting to learn

Until the day you came along

I used to just get lost
                                        D A
I only heard the things I wanted to hear
                                  D   A
It always seemed like no one cared
                      D A D A D E
But then you took the time
                                            D    A
And now I look and everything seems so clear
Bm                        A
