Does dreams always come true? This time,it's yes for me.

I should have post this long time ago but it's not too late to do so now..right? Before I got my Pmr results back.my mum and i dreamt that i got A's and 1B for Pmr,which surprisingly,came true..Most of you may think that it's good enough already but honestly,for those who really think that,you do not know me that well. Do you know that my heart came crushing down the moments my eyes landed on the only filthy B that seems to corrupt the whole certificate? I felt that it belongs to the trash bin and i never want to look at it ever again. The feeling of sorrow and disappointment filled my heart and i wanted to say sorry to my mum over and over again although she kept on saying it's okay. Inside,i know that she's just giving a reason to make me feel better..She kept on telling me not to cry but how do you expect me to when I can't even give her straight A's like my sister? I promise that I will never let it happen again,mum. I'm so sorry. I love you forever.
