I kid you not.
As the class was lining up for recess, one of the little girls near the back of the line asked Mrs. B., "How come you're wearing sunglasses?" Mrs. B. did not hear her but a cute little red headed boy did. He piped up and told his curious female classmate, "You gotta wear sunglasses or else you get cataracts." Then he said, "Do you know what cataracts are?"
(By this time, I am completely amused and trying not to crack up.)
Then, without waiting for a response from his new friend, he said, "If you get cataracts, the doctor will cut your eyes open." The little girl responded very seriously, "Oh! I don't want that to happen to me."
Then, not thinking twice about it, they went outside and played...without sunglasses. :)
