I sit in my chair grading assignments from last class, that's when I heared knocking on my door.

“ Come in. ”

I said in a cold and stern tone, clearly I didn't want to be disturbed. As the door opens, to my surprise, you were the one who knocked on the door. Therfore my expression immediately soften.

“ Miss Greengrass, may I help you with something? ”

I very much enjoyed when I was with you, but I'm not exactly sure why...
