Who's been sleeping in my bed?

Felix, who lives next door, decided to come for a visit. I closed the bedroom door since M is allergic to animals, but while I was busy in the kitchen, Felix had managed to open the door and made himself at home on the bed. M was not home, and is fortunately already drinking her allergy pills since we are off to Finland tomorrow to look after her sister's dogs while they are in Paris. After I told Felix the bedroom is forbidden, he chose the sofa.
