When you come upon a stranger, what do you see?  What you see determines what you think, and what you think determines what you feel.  Do you feel guarded?  Do you feel like stepping away or stepping up to say hello with a smile?  All of this is learned behavior—neither right or wrong, but take notice at how your programming keeps you from seeing that all is one.  Yes, the costume you wear hides the light inside, but the brighter you shine that light, the more it reflects off of strangers, making them more attractive to you.  Smile, why don’t you, and see what ensues.  You are looking not at a stranger, but at another expression of the same Light that glows in you.
