It's like everyone started screwing their cousins and we ended up with a culture full of retards. But y'see, we can't go around calling everyone and their mother a retard. Apparently it's not PC, and it's an insult to retarded people everywhere. These are the leeches of society who go on throughout life without a wit of common sense in their heads. Sure, they can be intelligent.
Common sense has absolutely nothing to do with intelligence.
You just cant teach it, and thats the problem. We get these doctors and lawyers who end up social morons because they weren't raised to use their good judgement. But see, even the dumbest a-hole on your block can have common sense. Here's a little analogy for you. Thats like a tard.
