Would u tell her

I seen a video of a woman sharing this story she got on the Internet. Her parent's made a surprise visit. I guess they decided to go out to eat so the daughter went to change real quick. when she came out she notice the special chocolate that she had on the counter was gone. Her mother has a bit of a chocolate tooth so she knew she had ate it all. So the question is do u tell the mother what that chocolate is really for. Or do u just wait to see what happens
