judge a book by its cover or not?

i dont know if i believe , " don't judge a book by its cover" i mean, when you see a creepy man, he's usually creepy, when you see a pretty boy, he usually acts like a pretty boy, if you see a girl wearing skimpy clothes, she's usually sending that message to you..i want some tonight!
so do people say don't judge a book by its cover so they get a second chance to redeem themselves and prove they weren't the stereotypically type? when really they were. it came to my attention today that we do things because we are so influenced by someone else, i mean you think you like something but really you like it because you know someone else likes it? am i getting off the track or is it too hard to admit to it?
so here i am in this whirl of thought, if we all acted like we do when we're drunk, how different would the world go round. i think the real person, slightly exaggerated i wont lie, is when someone is drinking. they let there heart pour out, they are honest..we are humans, we make mistakes so often and the bad people are the ones who don't learn from them...you trick me once its your fault, you trick me twice it is my fault.

...well theres some thought for the night. good night fashionistas...heres some photos for some dream making...my friends make my world go round..thanks guys!
