Snobbery is everywhere in Ireland, wether you have money or pretend to have money it's not a nice trait in a person.I think Ireland is full of people like Tigs who aspire to have more all the time. I grew up in a very working class family. I was the first of my family to go to college etc and now have a very well paid job so sometimes I move in these circles.
Anyway when I was much younger I was very impressed by people with a lot of wealth but eventually I realised that there is a certain set in Ireland who just go to the same places over and over again. The Merrion, The Westbury, adare Manor, holidays in marbella/quinta do lago and lately dubai. A ski trip once a year. A chanel bag. It all got so boring. I realised there was more to life and better ways to spend my money. Anyway what I mean to say is I looked up to these people when I was in my early 20s, not when I was 45!!
I think she grew up in a certain area and has been doing her best ever since she left to distance herself from her upbringing.
