That is my trick. And it works like a charm.
I am a patient person. Really. I am. Or at least I try to be. But some things and some people push my last button without even trying. I used to just snap, tell them they were wrong, yell back.. anything, but I made it known to them that they were annoying.
But, at some point, someone (I wish I could remember who!!!) told me that I needed to just count to 10! By golly, what a trick! When I feel like I am about to snap, I simply count to 10 (or whatever number it takes to get calm again). And voila, I am calm. It works. If you are an impatient person, simply count to 10, and then share the trick :)
Don't judge ;)
