Helen, I have lots of laffs with my adult peers and I can assure you that we never break down into imitating children. We simply have fun being adults? Sheeesh? Is that so hard for you to understand?
As for your other stuff about Tony Blair etc.... I am simply gobsmacked that in 7 whole weeks this crew in general, and Jonny in 'particlear' seems to be completely unable to have an intelligent adult conversation. I know that there are many adults like that who simply cannot sustain any conversation in which sex and mention of organs is not intrinsic, but if I were incarcerated with ppl for 7 weeks, some adult, thinking conversation and discussion would be vital. Or what's the point of being human? To that extent Jonny is what he clearly is, a total buffoon.
Get to see USBB3 if you can, and watch the HMs actually talking to each other and having some really interesting conversations and discussions, as well as time for fun and having a good laugh. But then they selected the US HMs with something other in mind to watch than a houseful of unintelligent ppl in conflict and getting drunk most nights, and tasks under challenging for 10 year olds.
