Recall

"Weird," I said as I touched the lock. 

It was the pin lock. 

So, although I was lazy, this file got me curious and that's how I began trying various pins. After a while father called out to me again. 

"Allen… Did you find it or do you want me to come…?" Father still didn't seem to be in a hurry so I continued my lock break. 

"Let's try this," it was their anniversary date.

Oh, so it was right. 

I started flipping a few pages. 

Since I couldn't read in detail I read only the heading and some of the underline things.

Effectiveness is 2 times more than N-methyl-D-aspartate (NMDA) receptor antagonist drug.

Pain receptors are much more sensitive.] 

That's all I could read since my father came into the room. 

So, I hurriedly locked it again but the thing that I noticed, at last, was that something related to the test subject. 

I wonder what that was about.
