Why Keep It A Secret? (GXG)

I dozed off in class as my memories turned into daydreams, I remembered an event. My bestfriend and I were nine, it was small talk you wouldn't expect from fourth graders.

We had been laying in the grass, motionless, I turned my head towards her and began the small talk in which I'm remembering

"What'd you get on the test?"
"I got an F"
"I got a B"

I sighed and opened my mouth once more

"Can you keep a secret? "

she sat up and looked at me, she nodded as curiosity shined in her eyes

"Don't tell anyone but, I like you."

she sat there for a moment, more than likely thinking of a response.

...

"Why Keep It a secret?"
