Im really intrigued by the way Nadia who is supposed to be so right on and perfect can have misjudged her alliances so badly and how Katie H who is portrayed in the press as such an obnoxious beast can appear to be so charming and such good fun. Both are really contradictory personalities.
I agree that Nadia is one of those nightmare mothers who's kids can do no wrong. She has needed so desperately to be in mother role in the house as it must be where her power base lies. However it has been a big mistake and many an overbearing, mothering BB HM has come a cropper that way. She has bustled and fussed her way around, bossing people in the process and at times been down right rude and obnoxious. Her rules and principles are more appropriate for the playground than a house full of adults.
All of us have to be 'two faced' or flexible in our dealings with others, otherwise we would be sacked or ostensibly ostracised from society. We are taught how to get along with strangers and quietly negotiate from birth, through school into adulthood - it's called maturity.
Katie H however much I loath her trite newspaper pronouncements is a 'grown up' and a charming one at that. She has been been witty and fun and stood up to the totally un disciplined child that is Perez in an adult way. She is is also clued up to the way Nadia's support is encouraging Perez's excesses.
Nadia has arrogantly decided that she is the only one who can care for/control/sooth him and has prolonged his stay in the house. This is her big mistake. Time to wake up Nadia and take your mindset out of the nursery and grow up.
