@liuzhou, let me add my thanks for sharing such a wonderful celebration with us. It's been delightful and I look forward to hearing more of your adventures on the rest of the trip.
And not to derail your story too much but I'd also like to thank you for prompting a trip down memory lane to my own mother's 90th. She didn't want a big party but declared that after 90 years, she wanted to celebrate all year and indeed she did! We kicked off that birthday year when I took her on a cruise in Australia and the celebrations continued all year long. I hope you don't mind me sharing a few photos of that happy year!
