^I absolutely agree, I mean how old was she when it was filmed, 16 ? 17 ?
Shes far away from home and as the Premier agents frequently stated themselves, they are the model's family, esp during fashion week. Remeber how you treated your family/parents back at that age ? Door slamming, being miserable, frowning etc ?!
Some people in here should indeed look bad at how they behaved when they were her age and then might take into account how they would have felt thousands of kilometres away from home.
Like penny said, she obviously refelcted on her behaviour and came to the conclusion that it was wrong, hence the apology at the end of the episode.
What - in my opinion - some people do in here is comparing her behaviour to an adult in todays businessworld which leads to the conclusion that shes arrogant, full of herself and probably oh-so-childish as well. Hello, she is a child!
Of course her behaviour is neither adequate nor polite but for gods sake, she apologized,
and having the guts to do so deserves at least respect, in my opinion.
