Too late to regret

I gazed out at the blue sky,while waiting for the teacher to arrive.Everyone was busy doing their own work,some were talking,doing their homework.And one particular girl was sitting at her place alone,thinking hard.Me.I once had a friend and those of you who are close to me,I'm sure you know who she is.She is the type of girl like Sharpay in High School Musical but I was of course,not like her at all.She loves shopping,spending money,etc.But I was totally the opposite of her.Still,we got along very well and we became best friends.We did everything together at school and I told her all my secrets and all my problem.But I was a fool,I thought I could change her,I tried to advised her when she did something wrong,and I know she doesn't like it.Then yesterday,all of a sudden,she started getting close to a girl,her enemy that she hates most.But yesterday,when I was about to sleep in class,I overheard her sayin something about me.Later on,my friend said that she was saying she hates me because I advised her a lot and even her mother does'nt do that.Then,at that moment I realised,nobody can change someone that easily..Unfortunately,she stopped talking to me and I too,did not talk to her.And now,I could only wish that she will not spread my secrets all over.When the teacher entered the class,the studying continued and I finally realised,it was too late to turn the clock back.What is done is done.
