Analysis of when its obvious

of different shapes and various sizes
a rainbow of colors may shade their eyes
the fact of matter still dont change
inside them evil still remains
despite what they show its always still there
let not the mask turn you blind
to attributes you may find
in people who hide their true self
secret agendas by them are held
if at first meeting you do see
danger and traces of deceit
excuse you immediately
then from their presence you should flee
