Apple of his eyes

My dad is a kind of person that never talks yo people.Whenever he came back from work,i had to make him a cup of redbull and i also had to get all his food ready on the table.
One day,as i was playing my phone,my dad came home.He went in the house and bang the walls like a mad guy.i was like"what the hell that just happen".My mom came to him and said ,"Oh dear,what had happened,are you angry with someone?".My dad again bang the walls with his hand.
In a sudden,my sister,Aisyah, came to him."Dad,why are angry?,ask aisyah in a polite.My dad then tell her that he's angry with his friend that cheated him on the project that they do together to take the cash of prize that they had won the 1st for the competition.His friend took all the cash of prize that they had won and left none for him,that's the reason why he's angry.
We were so shock for hearing that but we were more shock Aisyah my little sister that she could talk with my dad when his angry.She is meant to be Apple of his eyes.
