My Third Experience of Favoritism

This is the worst experience ever, my third experience of favoritism. 
Until now this experience is still fresh in my mind. 
This happened when one night my brother and I saw a colored green insect inside our house. 
It was so beautiful that both of us wanted to have it so badly. 
My cousin captured the insect and couldn't decide on to whom he will give the insect. 
He then decided to give it to me but my brother cried so loudly. 
Then my mother heard the cry of my brother and asked what happened. 
Then she asked me to give it to my brother but I insisted of keeping the insect with me. 
Until she became angry but still I insisted. 
Then suddenly she grabbed the insect and put it in my mouth and slapped me. 
It was so painful. 
It was not the slap that was painful, it was not the act of putting the insect inside my mouth that was painful. 
It was the act of favoritism that was really painful. 
I felt so helpless at that time.
