When Life Gives You Grandma And Her Clothes

Okay so I don't know the guy but let's call him James shall we. Okay so what happened with him is life. Hahaahhahhahah. Poor guy wanted to spend some quality time at his grandma's but before he could leave grandma insisted him to stay. There was nothing wrong till he realized he hadn't packed any extra clothes for sleepover. So grandma said "Oh, don't worry dear, I have something that just might fit you right." He is really looking funny in this and frankly I don't know why grandma thought that this will fit him???
