If only you knew...

Mac trotted up to the library... he had never been inside, and had no idea what books the place withheld. He brung up the courage... and went inside. He was greeted by Twilight Sparkle, the places owner, and sole proprietor. "Oh, good evening Macintosh! Can I help you?" She says, with a warm smile, and a slight tilt of the head. He smiles sadly back, a rare show of expression.

"Ah'd like ta check out a book." He replies. Twilight trots over the the shelves, looking them up and down

"Well, feel free to look for it, I have so many... Who is it for, if I may ask?" She looks back at him, eyebrows raised in a questioning manor.

"Mah self." Mac responds, looking up at the massive shelves. Twilight is taken aback... Big Macintosh checking out a book... for himself at that? This was a first. But she was glad to help. After some searching, Mac found what he was looking for, a text book on psychological defects. Twilight was extremely confused, looking from the book, to the stallion holding it.

"Are you sure you got the right one...?" He looked down at the book, then back up at the purple unicorn mare.

"Yes ma'am."She hesitated before ringing him up

"Well, have a nice day..." He did not reply, only nodding and trotting out of the library. The rest of that day, and until he passed out that night, he studied psychology. He still did not know what ailed him.
