Grandkids - they say the darndest things

My oldest grandchild had asked me in the past, "Grandma, how come you can't eat bread and rolls." Of couse I have tried to explain it like Grandmas do. But he had some friends over and he told his friends within earshot of his mom, "My Grandma can't eat wheat because she was stung by a bee." Those poor friends of his will be dodging bees just so they can have their PB&J sandwiches.
