Froog's solution to the problem of being repeatedly embarrassed to be asked by strangers in bars what he does for a living, and blurting out answers that are inappropriately long and inappropriately honest, such as "I don't have any work at the moment and I'm not sure when I'm going to have any again and I'm probably more or less unemployable and and I'm hating China these days and getting desperate to escape but I have no idea how I'm going to be able to do that" etc.:
"I'm in change management."
I wish I'd thought of that sooner. I'm going to use it next time.
