There's a reason a photo of a birthday cake is burning up the Internet, and it's a nice one. Lisa Sarber Aldrich of Michigan posted the image of the cake, adorned with the phrase "Happy Birthday Mandy," to Facebook with an explanation, reports Fox 5. The words look a little sloppy, as if a child did them, and store employees at the checkout summoned a manager to ask whether they should get a new cake. It turns out that an autistic employee did the decorating, and Aldrich insisted on keeping it. She says one cashier thanked her for accepting it in good spirits. Of her co-worker, she added, "Even though she's not supposed to write on cakes, you probably made her day." (More uplifting news stories.)
