He told my mom that i was playing a game in which people are naked!!!!
Then.....mom came and slapped me really hard and said:
"I need to check your computer!!!!!!!!!".
After that, my aunt asked my baby cousin to say sorry to me, and instead of saying sorry, he punched me in the balls and ran away!!!
One day, i was playing cricket with him. He threw the ball so hard, it broke the window of his own house. Then he started crying and when aunt came and asked what happened, he said "akmal broke the window glass".
I was like O.o and then i was bitch slapped by my aunt before i could explain.
It sounds like your problem isn't your little cousin, but the irresponsible adults you have to live with :|. "WHAT'S THAT, LITTLE KID? OLDER KID DID SOMETHING BAD AND NOT YOU? K. LET'S GO GIVE HIM A BEAT DOWN!"
