is or is not that into you

So I was reading an article about the supposedly difficult task of knowing whether or not a guy is into you.

I didn't finish the article, and I would not recommend any one else reading it. Why? Because one of the signs is "what you see in his eyes when he first looks at you". That means you have to be looking at him when he first looks at you. Because the first thing he thinks may be apparent in the first second, but after that it is likely hidden.

Nevertheless, that isn't what made me stop reading the article. The author ( a woman, which should have tipped me off in the first place) insists that you don't wear ANY rings. Any at all. Because men "can't tell which hand a wedding ring belongs on, let alone which finger".

This article should have been titled "how to know if an idiot is interested in you", and it would be something you would read to save yourself from idiots.
