there's a Danish saying that you'll get the truth from children, drunks and old wenches
Yup, they say that here too...
Kids have no knowledge or preconceptions about the crap that we adults let take over our lives, they just say it like it is and that's when you get the truth...
The only time most adults speak the truth is when drunk, then the next day they can cover their embarrassment by saying that it was the drink talking...
from the mouths of babes... as they say...
