"Since when don't you like him?"
She asks, her voice full of wonder.
I smile and sit there, trying to remember.
"Since I don't know when" I reply,
And her eyes cloud with confusion.
"How can you not know? It IS your decision." 
It is my decision, and I should know, 
But I don't. I don't know how
And I don't know when, because I've
Never really cared. Since I don't know when
Things have been different, 
Since I don't know when he has changed.
"Since when aren't we friends?" he asks
With a pout;
"Since I don't know when." I reply looking down.
"Don't know when? How is that possible?"
"I don't know when you started changing, so I don't know
when we weren't friends." I reply, walking off.
