A little girl was embarassed about eating a full guava in school that her mom had so thoughtfully packed.
So she took one bite and hid the guava behind her back and while walking in the playground, just so nobody coming from the front sees her and laughs at her for eating guava.
30 years laters, a little boy walked up to the stage to get a prize. He was having a chocolate in his hand which he did not want anyone to snatch off.
He hid the chocolate behind his back and climbed up to the stage, his backside on full display to the audience.
