The wicked side of me enjoyed that part too Lovesreading because it was unfair of the two older women in the next room to lock the adjoining bathroom when Eilis was so ill.
I found that considering the time the book was set in (1950s), Father Flood was not your a~typical coarse, sanctimonious, over~bearing priest, he was willing to help Eilis to broaden her horizons. The part where Eilis was asked to serve coloured ladies was nicely done, Eilis being young and not experienced, did not understand why there would be concerns, she accepted everyone for themselves, making eye contact,smiling, just being herself, I liked the part when she defended Bartocci's to Miss McAdams.
I think in some way Mrs Kehoe was using the basement room to her advantage, so that at one point Eilis would 'return the favour' but Eilis knew that Mrs Kehoe had other motives and let her know that she would not be returning the favour. I agree Lovesreading that it worked out well for Eilis in the basement room, she had her own space.
Miss Kelly had been told everything from Mrs Kehoe, which would upset Eilis but give her a wake up call about her husband back in Brooklyn and in a small way to put Eilis in her place, I felt that Eilis leaving Miss Kelly's shop offended Miss Kelly more than Eilis realised, also she would have noticed the change in Eilis, which leads back to Eilis being put in her place, which I thought was petty but some people get ideas in their head or they are just set in their ways, I think Miss Kelly was set in her ways.
I agree Lovesreading, Eilis needed to know that she had a reason to go back to Brooklyn and she knew her mother would not accept that she was going back for her boyfriend, it would be different if she was going back for her husband.
It was the right decision for Eilis to return to Brooklyn, she did not have much left at home and it was difficult for her to leave her Mum but her Mum made the decision that Eilis would go, the first decision I felt that her Mum had made on her own for some time but the ending was left opened, that Eilis may at some point return home to Ireland with Tony.
