Ms. Tan is making all the arrangements and will accredit our visas. She says she wants advice.

Young, wealthy Chinese will start to be more adventurous, she says. When Barack Obama released visa restrictions on tourism to the US, innovative agencies created options like a week in a summer camp in Florida for Chinese children, white water rafting in Northern California and so on.

She has asked us to come up with other ideas.

I am thinking we could put together a literary visit, like plays in London and Stratford, with smart students on hand to talk them through the life and business of a theatrical company in Shakespeare’s time.

Or a political visit which would take the visitors into the City of London and show them things like the Futures Exchange, meet MP’s in the Houses of Parliament, take them by Eurostar to Brussels to speak to the European Commission and see the European Parliament.

She liked the last idea. I was pleased. Henry has made me curious about the European Parliament.

I am getting to know new people through Maureen, like her younger brother Ken, who owns his own firm. His firm provides luxury toilet hire for big events. Ken runs the firm with his wife Felicity.

I like Ken. He does not want to be super-rich, just well-off. Ken and Felicity know exactly what they want to do with their money and their firm is the way they will earn it. He told me they would one day like a boat with a mooring in Dartmouth.

They take a pride in doing what they do and doing it well.

Ken and Felicity are genuinely passionate about the disease and indignity facing people in poor countries without indoor toilets or privacy. They write about it in their blog.
