Heart Break

Why? This is only the 3rd day i am back from Kuching. Isn't that suppose to be a happy time? Why am i feel so sad now? I feel so bad that i din teach my brother well. He is now 17th, why he still act like a child? When will he become mature? When will he realize that he is wrong? Why every time he want other people to accommodate him? I do not understand, even my little brother can think wiser than him. Sigh. I hope he will be mature someday. Don't break mom and dad's heart. I sincerely hope that!!! Hope the time will come soon...
