So I was in the hospital earlier today, asking at the front desk about a friend. I heard this voice ask the receptionist if he could get an appointment, as soon as possible. I couldn't see anything, however, and was wondering where the guy was. Then I heard "I'm suffering from temporary bouts of invisibility," same voice. I thought to myself, well, that explains that. I was waiting to visit my friend, when I heard the receptionist call out, "Wherever you are...uh...you'll have to come back. The doctor can't see you today."
