Thanks for passing on your simple way with beans - that's my favourite way of preparing everything ;-) lol will give them a try.
Onto why this dread of travel occurs, I think there's lots of causes with so many reasons, it's a tough one to answer. I used to love the journey as much as the holiday but now I always end up ill with the stress of it!!?? Crazy I know! I've always suffered with travel sickness too and now end up with migraines on top, there's just no hope for me lol. For me though my biggest prob stems from a long period of suffering with anxiety and depression and over time I stopped going out completely. Once the illness had improved I had to almost start over with learning to go out again never mind going away. Won't go into too much detail (it's boring lol) but think it's now about being in unfamiliar situations/areas & I just don't like the feeling of not knowing where I am!!?? I guess it's all about working around what causes the problem to alleviate the stress as much as possible and stepping outside your comfort zone for the greater good. Keep hoping that the adventurer in me will return one day lol.
Have you spoken with your mum about why she thinks she no longer wants to fly? There could be something small or big that triggered it, know my mother in law became averse to flying as she got older & with her it;s about claustrophobia, she used to go abroad 2-3 times a year but that stopped some years back. Hope your mum finds a solution to the problem anyway whatever it is, although she may just not want to fly :-)
I am glad you are enjoying London so much. I agree with you, it is incredibly diverse. Each time I visit it is like a new experience, although each time I have to fit in a visit to the V&A!!! I just love that museum! The market is the Real Food Market. Here is some information about it: http://www.realfoodfestival.co.uk/market s/real-food-market-at-southbank-centre I hope you'll go and buy a pumpkin strudel this weekend! ;) They had lots of fantastic vegetarian things on that stand. Enjoy!!!
