Seems as if it's almost expected.....

I have been reading a few secular books while here in the USA (relatively tame ones), and sometimes watch a bit of TV that my mother has on. One thing which I have noticed is that in almost every story, there is at least one character who has been unfaithfull to their spouse, and in general that reactions are pretty "ho-hum". As if this is almost expected.
All I can say is PWWEEWW!!!!
