C                 F     G      Dm
   We got these days of summer to
             F    G
Remind us of each other
C                F     G      Dm
   The time we have to spend apart
             F       G         Am
Will keep us in each other's hearts
Am                     F
   I'm hoping that the good old days are
Em               Em7
Something I will dream about at night
Am                              F
   And It don't matter if it's sooner or later
G
I know that it's gonna be all right

F                 C
    I don't wanna see you go, but it's
Am           G
Not forever, not forever
F              C
    Even if it was, you know that
Am            G
I would never let it get me down
F                      C
     'Cause you're the part of me that
Am              G
Makes me better wherever I go
F                       G
So I will try not to cry
G
But no one needs to say good-bye

    I don't wanna see you go, but it's
Cm           Bb
Not forever, not forever

So I will try not to cry
Bb                           C
But no one needs to say good-bye


This is the little riff afterwards:


e--8-7-3-0------0------------ |      (notes: high C, B, G, E, D-C-D-E-D-C)
B----------3p1-3--3p1-------- | 
G---------------------------- | 
D---------------------------- | 
A---------------------------- | 
E---------------------------- |       x2

e--8-7-3-0------0-1h3--0h1-3--0h1-3---5--7--8- | 
B----------3p1-3------------------------------ | 
G--------------------------------------------- | 
D--------------------------------------------- | 
A--------------------------------------------- | 
E--------------------------------------------- | 

(notes: high C , B , G , E , D , C , 
D , E - F - G , E - F - G , 
E - F - G , A , B , high C )

Repeat that little section again and then end on a C chord to make things easier (It 
does modulate loads whilst Harry's talking until it goes into Gotta Get Back to Hogwarts, 
but for the purposes of sticking to one song, just end on a C)
My brother plays guitar, I only play ukulele, so I have no idea really how to tab 
things.. 3p1 means pull off the 3rd onto the 1st, and 0h1 means hammer onto the 2nd from open. 
I don't know if that's how people do it, but it looks okay. XD

I put some serious effort into this, make good use of it :)

Have Fun
