I think you could well be onto something there, as there's clearly something missing in her day to day life. The cruise isn't until next January, which is a long time ahead. It could well be there's nothing much on the horizon for her until that time comes, hence why she's buying stuff with Christmas in mind now. I briefly thought that perhaps due to financial constraints that perhaps a holiday this year was off the cards, but let's face it, with the amount of money she's frittering away on what seems like a daily basis, she could've afforded a couple of weeks in the Bahamas! Yes ok, she's probably been there, done that, and most certainly will be going there next year, but perhaps a city break somewhere would help - who knows? Goes to show that having money to spend does not create happiness, and seeing her out of control spending is kinda sad!
If she was a part of our forum, I'm pretty sure that someone would've picked up on this, and maybe she'd be able to talk about her worries. On Qurio, they don't care less unless you're spending!
