My Most Trusted Friend

Trusted.
That is exactly what it means.
Although, they weren't very trustworthy to begin with.
You know the friends that knew each other better than anyone else?
They ended up leaving each other at some point.
But, no one ever said it would hurt.
People always said that it was as if they dropped a big burden.
That was because they stopped caring for them.
What if the "burden" decided to come back?
And you decided to believe they changed.
