I found the emails irritating rather than endearing. She sounds pretty entitled and spoiled to be honest.
My daughter worked and saved for a year before she went off on her travels. Money got very tight at times but she never asked for assistance (although I would have in an emergency) as she takes pride in her independence.
Travel can be great for growing up and being independent, but not if your rely on Mummy and Daddy to bail you out all the time.
I'd love to go to S E Asia but I fear that the hordes of selfish young adults like this girl would drive me batshit.
