tsk tsk... If you're going to talk in English make sure it's grammatically correct. You need lessons. And I agree with everyone that you're the one creating problems in this thread. If you truly are a mature person, you'd be more critical of your words and be more constructive rather than destructive.
With the way you're acting, you're just showing everyone how completely immature you are regardless of your age.
I was enjoying the thread then you came along. If you're here to teach how to hold the sticks right, create your own thread at the 'Music school' board and teach.
