This is my Ni tan story: 
a peasant  guy work very hard and finished late in the morning， that day he finishes his work as   ploughing  the soil very late and he is so hungry and angry .  afterward his mother comes with her sticky rice blanket and some food.    '' Boy, it's time to have a breakfast "  says the guy's mother
the guy stops to work and start to approach the place to eat, he is so angry and after seeing a small sticky rice blanket which his mom brings to him,  He is so angry and hungry to see a small sticky rice and food  and suddenly attacks his mother by using a yoke  ,an old lady suddenly falls down and stop breathing.
Meanwhile the guy started eating his breakfast with a small sticky rice blanket.  lastly he finishes his meal , but   there are lots of sticky rice in a small blanket  which he couldn't finish it all. now he thinks about his mom and goes to hug her, but it is too late that his mother was already died .

the guy is so sad and regretful about what he did to his mom.
