The Wardrobe (Other Friends)

Although we have always lived quite isolated, my brother Waylon and I never felt alone. We always played together and had lots of fun! This year I started attending a new school which only allows me to go home once a month. I was afraid Waylon would feel alone without me. But apparently he wrote me back a letter that he befriended with some creatures that lived in the wardrobe? He wrote me a letter that, thanks to them, he now has many friends to play with whenever he wants. This dawn, when I arrived, I was told from my mother that Waylon is sick and has been confined to his room. I absolutely have to talk to him and make him explain what happened.
