Hidden stress

"When deeply stressed, I become even more serenely calm and unflappable than usual. It happens gradually. I’m a fairly laid back chap usually, so nobody (including me) notices the change. I shrug a few things off. I don’t let things get to me, but over time I can end up letting things slide that I have no business letting slide. Or absorbing bullshit that I should be challenging and confronting. Or, worse, failing to help other people when I should."
