Dressing up like Waldo doesn't make John any less blatant.
John is childish enough to let a blind friend look for him all over the room. Of course, he's also childish enough to giggle at his own joke, immediately giving himself out.
Other note: You'd think he learned his lesson after spraining his ankle in these shoes, BUT HE DIDN'T!
Aghh! You are so good at small story/character details. Love it.
Is this about the shoes?
