Definitely not. Julie was born in North London, not far from where I grew up. Certainly an "ordinary" area, and it wasn't/isn't uncommon for families from that area to move out to Essex later.
Which part of north London are you referring to, MrsWah?
As a Londoner myself I know that there’s some tatty parts of north London, but also some incredibly beautiful parts where properties cost millions. Highgate/Hampstead, for example. There’s also some very nice parts with tree-lined avenues, gorgeous Victorian/Edwardian/Georgian houses in less salubrious areas...in fact, even the tatty parts are expensive.
It’s irrelevant, anyway, as you don’t know what Julie’s financial circumstances were. You don’t know if she had savings; a small inheritance from one of her grandparents...you’ve not idea. You don’t know if she maxed out her credit cards to travel...you’re making suppositions based on what you IMAGINE.
How do you know she didn’t have relatives in Canada? It isn’t the first country that springs to mind when students travel on a gap year...
Incidentally, Julie met her husband in 1990, in either England or Europe. After they married she moved with him to Canada as he was Canadian and they decided to settle there.🤷♀️
