Thank you for the silent downvote, Downvoter!
I invested my experience and time to write the message. You? You pressed a single button, and basically told me: Fudge You.
Well, I am sorry, but Fudge You, too, then.
Though, seriously I believe, in such educational cases, silence is unfair, devalues contribution, and degrades the whole sense of education.
Therefore, please do consider actually stating what you believe is wrong, why it is wrong, and how would you improve it.
