Question

guess the song:
Goodbye to you, my trusted friend
But we've known each other since we were nine or 10
Together, we've climbed hills and trees
Learned of love and ABC's
Skinned our hearts and skinned our knees
Goodbye, my friend, it's hard to die
When all the birds are singing in the sky
Now that spring is in the air
Pretty girls are everywhere
Think of me and I'll be there
