Everyday when we go to school, walk to work, cross the road or even go grocery shopping, we see hundreds of varieties of people. Small people, tall people, old young, skinny fat etc... Some may greet us with a smile, others may give us a frown. We tend to often go to the nice pretty young lady by the help desk, other than the big fat man with sweaty pit stains. A first impression is important, it's what first gives us an idea of what the personality of this person is in our minds. The young boy we see smoking in the corner, is undergoing huge family issues after his parents split up. That old lady working at Burger King is trying to fulfill our orders quickly so she can take both her kids to soccer practice. This old man sitting beside us in the bus, despite his nasty smell, saved the lives of 3 men in the Vietnam war. All this isn't written on our faces on our expression on our skin or our body shapes, this information is on the inside.
It's what we do that makes us who we are. And what we do, is in our memories, not our appearances.
