I Heard That You Can Know About People Without Seeing Them. Is This True?

Now I do believe that after a conversation or maybe being around a person our senses can kick in. I know there have been women that I just did not get a good feeling about my husband being around and sure enough my intuition was correct and they were trying to sleep with him.

Yes as you can know them by chatting in the internet
