looking back, I think we let you down.
we should have required you to clearly define what you need.
then had you refine that
then refine that.
(we are often too quick to offer answers to questions that are not clear.)
by the time you could logically describe what you are looking for, you would have been able to find the answers.
I keep telling my son that if you understand the question. every word in the question, with full conceptual understanding.
then you also know the answer.
if you cannot figure out the question, you can only guess.
