Actually you have hit on a bugbear of mine. I regard "IMO" or "IMHO" (as though that is different) as redundant. It should be absolutely clear that you are stating your opinion if the subject is anything other than you can prove as a fact, which is clearly the case when providing superficial psychological analysis. IMO "IMO" is a waste of time.
Just to indulge for a second, it seemed to me (there you go) then when Irma left she did not really make an attempt to interact with Anna with whom Irma seemed quite close but she gravitated towards Layla who had seemed somewhat self-obsessed when she arrived but that Irma had made real effort to bring into the group. So at one point Ilona thought of Layla as a rival and then the instant the group 'mother' (I think that is a good term for Irma because she really seem to care about being inclusive) left Ilona felt the need for a supporter.
With the arrival of Danaya it did not take her long to bond but this time Ilona started to dominate making sure that while she was awake she would spend as much time in her company as possible. Whilst Ilona has not stopped cooking she has gone through long periods of staying upstairs in Danaya's room while being brought food and drink and seems to provide very little of the cleaning effort in the flat. I am not saying it is a mistress/servant relationship but there seems little question who is control.
Now Adele has arrived and does not seem to be the type to be pushed around, Ilona spends little time in her company, although they do seem to be getting on better today, because she does not need her yet and maybe her tastes are different. It is interesting that she has thrust porn in front of Layla's and Danaya's faces, when this is clearly only a prelude to nothing more than horseplay unless it is "Look how switched on I am, shouldn't you be as well?" and I do not buy the "Oh I innocently discovered this" as though she was doing something naughty.
Sorry to anyone who read this before, I do not know why I called Adele, Irene :-[
