We have been back from our UK trip a couple of weeks now. We ended up seeing 64 people in 4.5 weeks, so we have definitely come back for a rest! We had a great time over there and were sad to say goodbye. I always find that every time I visit it unsettles me for a bit when I come back and then I get back into the swing of things and normal service soon resumes!
We were sat in a restaurant in St Pancras train station in London and I overheard a lady on the next table mention Adelaide, turns out they live in Adelaide about 15 minutes from us. No doubt at some point we will bump into her in Adelaide.
As I mentioned it has been 4.5 years since we were last over there for a visit and nothing much had changed, apart from all the solar panels (we reckon we saw more over there than here!) and wind turbines everywhere.
