Small is petty, insignificant and immaterial, well! may be not. Most important and big things are well presented, polished and masked in politically correct connotations but it is the small things- words that are a slip of the tongue, involuntary gestures- that show a glimpse of the real person and unmask the hidden personality. Though people are too complex to be stereotyped but small acts of kindness or cruelty or mere indifference towards others are the key to decipher someones behavior.
Most big things are draped in pretense and the real world around us is in the small things.
