There are so many ways to react to strangers. It is sort of like responding to yourself. You have to respond to thoughts, criticism, positive ideas, negative thoughts, spectacular life ideas, judgment of yourself and by others, and so much more on a daily basis! But it is the acceptance of all these things into one grand idea that what you tell yourself everyday will lift you up or tear you down. What you think about all day is what you end up manifesting. You are not a victim of your thoughts but instead a decipher. Therefore, if you see yourself in others, you are in fact deciphering them to make both parties happy - Yourself and your thoughts, or yourself and the STRANGER. Hope this makes sense for all of you.
