It's funny how strangers can pass in front of you every day and all you see is a flat shadow, a vague outline, not noticing any of the details. They move in a gray crowd, always looking the same and acting the same, simple caricatures of who they really are, but once you get to know them, you notice the specific, tiniest things, you pay attention to the intricacies of their personalities, their habits and particular ways of walking and talking, the subtle changes in their appearance and dress.
