My teacher angry

last month at my khmer school i had make my teacher was angry me.My teacher's love me like her children because am a good student and smart student in the class. one day i had a new friend and she always didn't came school but if she came school she didn't study she always make noisy in the class. when she do like this i still make friend with her then my teacher told me "u shouldn't make friend with her "because she afraid me the my friend but i didn't listen her advice. From the day that i make friend with her my study is very poor because i didn't try to study but I try to make a bad student in the class then my teacher very angry me and she didn't talk with me like before. when my teacher do like this to me am very sad and i think shouldn't do like this i should try to study . when i go to study i said to my teacher "teacher i'm sorry now i know am wrong now i promise with u i stop do like this and i try to study the same before"then she smile and said "ok u know like this is good please stop do like this and try to study" . when my teacher said like this am very happy . Now i try to study and i have to be a good student again. ;)
