Again I had to shift the lunch one week as I was in the USA – and I like to be present to be sure the lunch is running well. My jet lag did not bother me but I had to run to SOS Hospital in the morning, to take care of what looked like a bronchitis. Indeed there is a virus running around in Beijing, not only affecting kids, see this article:

We were about 25 with some of friends not turning up because of meetings and health issues.
Next round is 6 May, back to “normal”, the first Friday of the month.
