true reflection

a friend once made a very good analogy of mirroring."If two persons come out of a building on fire,one with a clean face whilst the other ash covered,who do you think would wash their face first?" Answer - "The one with the cleaner face!" Why you might ask- simply put ,if others are a reflection,it is never clearer than in this instance ,when the one with the blackened soot filled face looking at the clean faced person,assumes ,"my face must be clean too." My exploration continues as every time I see myself judging a quality I dislike in another,I jump at the possibility that ,it just might exist in my dormant character,only I fear acknowledging the same.
