What a shame that such a long and thought out post is lacking in so many areas "sigh". Michael and Brad arent/werent the only two HMs discussing her so called "hard life". Ive seen most of the HMs talking about it at one point or another. Also, what does Michael and Brads upbringing have to do with Estelle's life? Your post is chock a block full of assumptions, and we all know what happens when we make assumptions, dont we!
Estelle came into the house and thought that acting all cute and quirky would attract attention, and the HMs would think she is soo funny. The fact of the matter though is that they all could not stand the way she acted and carried on. This is why she has been nominated so often and by so many different HMs! She is basically an attention seeking, bullshit speaking pain in the arse. Unlike your post, that last sentence is not an assumption!
Whatever Michael says about Estelle is agreed to by the other HMs. None of them like her. There is a reason for that, and its not that 16 ppl who have lived with her 24/7 are all wrong. They are in fact just doing what comes naturally. That is they shun ppl in a group who act in a way that either irritates and/or frustrates them.
Sorry to shoot you down, but maybe next time you will post something a little more factual, rather than your diatribe which is full of assumptions
