please forgive me, i never want to lie to you

i feel so sad now, i write this blog with crying, because i had a fight with my best friend. i have been known her since i was kid, we're in the same school at the primary, but different at junior high and senior high. all because of i lied to her. i must participate at Kawai Music Concert this sunday to sing, but she won't, because some of Kawai's representatives said that i shouldn't say to her that i will be in the concert, why? because they don't want if the concert is ruined by her because of her who usually doesn't come to the class, or so hard to have a practice time. i followed their order, and last hour, i met her at my piano class. i was practicing with my teacher because he will play the piano for me when i sing there, and she asked, "why do you practice singing in the piano class?" and i suddenly stunned, then i said that i will sing in a school farewell party so i must practice here. but my heart didn't want to lie to her, because she is my very best friend and i never ever can lie to her. after the piano class, i sent a text message to her to say sorry, but it has already been late. she already knew that i will participate in that concert and she won't. she must really hurt, and she is so mad to me. i'm a girl who can't receive a condition that i have a fight with my friends, especially my best friends. suddenly i cried when i was reaching home. i talked to my mom and she called my friend's mother to explain the problems, but my friend was really mad and she wanted to reject her mother's cellphone. really, i feel so sad and so sorry to you. i really really don't want to lie to you. because i know you never lie to me. i'm so sorry, really really sorry.. please forgive me... you're the one of some my best friends that i ever had..
