Just as we were about to visit the Houses of Parliament, I noticed Dame Tanni Grey-Thompson in the tube (metro) station! She is a very famous Paralympic athlete, having won 16 medals over the years, and now a Baroness (for her services to sport) with a seat in the House of Lords. She featured on all the Olympic and Paralympic tv coverage here as she is an accomplished TV presenter as well as being a parliamentarian and retired athlete! I explained all about the Paralympics to my guests (we know that there was disappointingly little TV coverage in the US for the Paralympics which was beyond fantastic) and she then described to them her role - she was so charming. She also was more than happy for them to have their photo taken with a celebrity!
