I feel very upset to my Uncle

I totally upset with my uncle treating my po po this way, once i get to see he treat my po po like that i feel my heart break into pieces. My po po treat my so nice and care for us, the way she treat us, the way she bring us up is just like she is my mom. I was very angry that time my uncle do something that really can hurt my po po but I didn't do anything to stop it, cause he is my uncle. IF for my attitude in my secondary school i really will batch him up till he feel down, Thanks to my gf was beside me that time and i didn't do anything is because of her and i feel sorry that scare her. Actaully i want to say this sorry when you are with me that time coz the senario is just so terrible and make up feel very upset. I don't really know what happen in between, so that why i don't dare to do anything. If i kmow the problem is because of my uncle who make it out and yet he treat my po po like that, i really will batch him up to the max with no mercy. I will do that if she treat my po po again like that. Probably i will be going back more often to my po po house, just hope that this thing will no happen. Even i am busy with my current project, i will surely going back to my po po house!
