(I have psoriasis, a hereditary condition which leaves me with large red patches on my scalp. This occurs while I am waiting in line at a convenience store with a woman standing behind me.)

Customer: "What’s wrong with you?"

Me: "I beg your pardon?"

Customer: "Those ugly blotches all over your head. What do you have?"

Me: "Oh, it’s a highly contagious flesh eating disease. Very painful."

Customer: "Oh my gosh! Really? How contagious is it?"

Me: "Well, you probably already have it."

Customer: *rushes out of the store in a panic*
