Looking at someone life through the eyes of a stranger is it fact or fiction...

Living your life through the eyes of a stranger do they really no whats going on NO they just give thee impression that they do.Those people just judge from a distance trying to recreate your life but don't exactly have all the pieces so they just fill in the missing parts with anything to create a full picture rather it fits or not.They are deceivers on the outside trying to get in they need to becareful because they house maybe made of glass too. Is it fact or fiction that what you see is what u get?
