Everyone, Forgotten

In this life,
In these days,
people come and
people go away.

They say hello,
They say goodbye,
You're left alone,
You're left to cry.

Where'd they go?
Why'd they leave?
When'd this happen?
You're left to grieve.

I guess that's why they say:
You're better off alone.
What good are friends?
If in the end, they're gone?
