So basically they were presented with an opportunity, purely coincidentally, where Esme (and Isla if she wanted) could have had an experience that they would never have forgotten - it really would have been a once in a lifetime opportunity for them - and the “set for life” parents didn’t let this happen?
The fact that it was a mock experience was just perfect for them (clearly would not be appropriate for their level if it was a bonafide audition). This is the type of experience that makes life long memories for children that they treasure forever, not the eleventy billionth watermark and theme park experience! If my children were into dance and this kind of opportunity landed in our laps I would turn myself inside out to give them this experience. Despite what anyone might feel about these children they really are just children, who are the products of their parents’ upbringing (I actually think they seem to be great kids considering), and I feel very sad for Esme that this experience wasn’t given to her.
