I can keep it all in, and very well-hidden too. People comment on my patience and good nature. Heck, I've even been called serene.....twice! HowEVer, once I've been pushed and pushed as far as possible down my "road of amazing tolerance" I will explode, with alarming consequences. I find that if you catch people unawares, and they don't think you have it in you, then it has a better effect. The people who throw wobblers all the time have no surprises left!!!
Sorry for your cr@ppy day, dot - hope things improve soon x
