Why does someone assume a attractive person can't do no wrong?

They associate a person's looks with what they assume their personality will be like. When they have made this judgment it can be difficult for them to face the reality of how the nice looking person is really behaving.

Perhaps its more prudent to enter friendships with as few judgments and expectations as possible.

kanye west said it best in All Falls Down, "the prettiest people do the ugliest things".

their attractiveness clouds up the brain cells..we would close our eyes be a totally different story

for example Debra Lafave. The teacher who had sex with her student back in 2005. I think the court system was too biased toward her. If it had been a male teacher, he would have done some serious time.

I guess if you are beautiful you can get away with anything.

I never assume that.
I do however try to find something nice about everyone I know.

because they dont think they are wrong

because people base too much on beauty......but beauty is really only skin deep!
