Years ago, when cigarette ads were allowed, the company got some flack when the ad said, "Winston tastes good LIKE a cigarette should."
Hamster-Bamster, I do a lot of cringing in Psych Central, on facebook, etc. Notice that a lot of folks don't put the comma after nouns of direct address, too. Pachy had a thread awhile back in the "things that matter" forum about the issue of poor grammar. If you can access it, then I think you can identify.
I agree that as an official test, the sanity one should use correct grammar. However, in regular posts, I have just given up on getting upset. I am more concerned about the content.
By the way, this post is in regard to the wording of the test. It doesn't relate to whether we accept ourselves as insane or not insane, as someone suggested in an earlier post on this thread.
