Tough time with Piano today

Today QuocNam had a hard time with a Piano lesson, and couldn't thru the first line for a long time. He must be tired. I tried to get him thru with it, but he seems to shutdown and want to go bed. I was so mad and told QuocNam that I'm going to donate the ipad so he won't be able to play and not doing homework or practice piano. QuocNam did cry and told mom to give him breakfast every morning so he can be smart and learn the lesson better... Btw, yesterday we came over to Williams's house for Noel's dinner. When leaving, thang Liem told QuocNam to reveal his secret, but QN didn't tell him so thang Liem got mad. They struggled and little bit and thang Liem got a yell from his dad and he cried too. next morning, he texted Thao and said: he didn't want QuocNam to come to his house, and he won't want to come hear and see QN any more...Thao did say sorry for the misunderstanding but thang Liem still said "no way"...
