In life there is one fatal mistake that most of us make and that is judging a book by its cover. Assumptions and preconceived notions can consume our thoughts when we first meet new people. However, those thoughts can be challenged. I must admit abstaining from preconceived notions is extremely difficult especially within a society that puts labels on everybody. These social classifications can inhibit our interpersonal relationships. What you will find is that preconceived notions are usually false perceptions of individuals.
A real life scenario of falsely judging a book by its cover is somebody who has tattoos, wears his pants below his waist, and works at a local Bodega but is perceived to be a criminal. This young man actually turns out to be a lawyer. Then there is a scenario of a woman who dresses appropriately (in a blouse an dress pants) and whose daytime profession is actually drug dealing. Here we see that one's apparel can be quite misleading in regards to judging one's character. Another common example regarding clothing is a girl who dresses provocatively and is perceived to be promiscuous but is actually a virgin.
Another feature of an individual that can be misleading is somebody's place of residence. For instance let's say you meet an older white male who is part of a country club, wears brand name clothing, and speaks with a refined suburban accent. At first glance it may seem like he may be a Westchester County resident or reside in Greenwich Connecticut but he is actually a resident from inner city Philadelphia. On the contrary there may be a young black male who speaks in slang rather than proper English, wears plain clothing, hangs out in a Bronx park where he plays basketball during his leisurely time. This guy may appear to be from the Bronx but actually lives in Bronxville, New York.
