Imagine that you are walking with your husband in the mall and a woman walks up and says hi to him. She appears to be extremely familiar and engages in conversation for a moment or two. Now picture that this woman is someone that you have never seen before.  Does your husband introduce you? Does he tell you who she is or does he quickly tell you – oh she’s just a friend? This is a friend that has appeared out of thin air. If this person is very familiar with your spouse, they should be familiar with you too. Beware of people who just “pop up” out of thin air. Also, if you only meet friends of your spouse when they accidentally bump into them, they may be hiding something.
