Analysis of They’re gone

Isn’t it crazy all the friends we’ve had
Now they are all gone and it’s kinda sad
I use to have a friend I could sing out loud with.
I really miss a friend I thought I’d never miss.
I had a friend who’s nick name was turtle
I had a friend who tripped on life hurtles
What happened to my friend who played guitar?
I guess someone else left for the stars
Remember that friend I’d always scrap?
The next day there we are patting each other’s back
My friend I went fishing with all the time,
I think they reached the end of their line
Where’s my friend that would write a lot?
Oh wait that’s me, you probably forgot.
