They (his colleagues) don't care that he has less morals than a horny rabbit. They don't care that he is unethical. They don't care that he lied. They care a little that he got caught. Mostly they are concerned that he lied very badly.
actress Janeane Garofalo told Bill Maher recently, "everyone lies about sex"
The above struck me. Did she really say this? I believe that she claims that her sex is female. If everyone lies about sex it would mean that she is actually male. That may explain her attitude. If I were a male that looked somewhat like a female I'd be in a bad mood all the time also.
Of course I know she meant sexual activity, but I think she's lying about everyone lying about sexual activity. I'm pretty sure that I've never lied about sexual activity.
