Man, everyone has worldly desires, but your ass is not clean. Then you have to bear the embarrassment caused by this, if your brother and sister. It's time for you to tell a white lie, for example, the fat boss who developed photos actually put this picture book in my picture and took it away by the way.
Big brother and big sister may laugh it off without any explanation.
In front of you or pretending not to see it, it may teach you a good lesson. Of course, if I can tell you something, you may feel better.
