To get an angry just because of small reasons. 

That small reasons trigger to our mind and it changes our mood, present thought process, mind distracted. Within a second destructed mind lead to anger and ends with violence. For that seconds of period of time one unusual human being come out from us. Expression of temperament to be executed as shout then beat a person. At that point of time everything disappear from our mind like for that person we have respect, love, importance. etc. Do that person is really getting right things from us?? Do that person deserve that shout and violence???

If we talk about particular one relationship - husband wife relations 

where 

* Salt is less in food
* 5 minutes late for serving food  
* Child is crying, He/she should not cry, fall down 
* My clothes are clean
* why are you asking for money money
* My In laws are not good
* Why you give a birth to girl child
and much more reasons can be added.
That leads to shout, physical or sexual violence..

Can we see these things around us?? 
If we see how we react is important. 
Do we run away from them or we stand with them.
