I am Naina, my father passed away in 2012, since then my brother is too voilent on me on my mother, he rules over us and scares us by being voilent, he beats n slaps me and when my mother tries to protect me he pushed her n warns her that he would raise hand on her, once he even raised. He gets angry for silly reasons like about food having less salt, food not prepared, complaints on normal food, scolds for driving slow. Lot of silly reasons. All silly reasons. He don't earn for family, nver helps instead wastes all money my terrifying us. I'm the only one earning to run the family n he is 28 yrs old and stil all the time plays games insde room. No one can say anythng to him. He slaps n beats when he himself takes the fight to extreme level. My mother protects me when he beats me, but he scares her saying he will raise hand infact he did once n pushed her. She was a cancer patient. I have complained to local nearest police station once and once with Vanitha station, it was of no use.
