1) when I bumped into a random stranger while walking, he said I looked familiar. I told him about some of the career fairs I went to and probably met him there. When I mentioned I was looking for work he gave me his business card about an "E-commerce opportunity" and to call him.
2) I got cold called from a former coworker. I was suspicious, and they proved true when he mentioned that he noticed I was always looking for more work to do and a "go getter", unlike some of the other coworkers who just surfed on the internet. I called "BS" in my mind, because our offices were never close enough for him to see what I was doing. Again, "E-commerce opportunity" was the same hook used.
On both occassions, that's what it must've felt like to have your "spider senses tingling" or that "jedi sense" of something is amiss.
