One that eludes you I guess. I can't make you be more specific. If you want to spell it out in an emphatic and concise opinion, go for it. Otherwise, I see it as a vague generality and likely strawman.
At first glance, knowing how to read is a common place thing, and really it is...at least that was what I thought. Little did I know I was being ignorant and underprivileged in my knowledge of the alarming statistical figures which show that many individuals (ranging from ages 8-adulthood) are not properly educated in terms of remedial reading, grammar/comprehension skills, interpretation and other such necessary terms to get through the world today.
I am sorry you fall into that group. I have no more time for games with you.
Unless of course you are 8.
