Analysis of My mother was right

Thinking back to childhood and
the friendships I thought I understood.
When really it was all a lie,
Just part of time needing to pass by.
My mother said one day we would all grow apart.
I just knew she was wrong, deep in my heart.
A bond so strong, stronger than blood
A natural born sisterhood, not so unheard of.
We did everything together, never apart
these girls were the biggest piece of my teenage heart.
As time passed though, things were done and said
I couldn't believe this was happening, had it all been inside my head?
These girls I thought I knew so well, I would have died for.
Turning thier backs on me, friends no more.
All over a guy, that I never even saw
But he was enough for them to end it all.
After years of friendship, sharing clothes and each others beds.
Five years, then ten, not another word has been said.
Guess my mother was right, when she said it wasn't real.
Crazy though, how our teenage souls can feel.
