simmering beneath the surface

I realized something today. There are 2 kinds of people in this world. The kind that explode in your face when they're angry, and the kind that lets the anger simmer beneath the surface and looks pretty calm on the outside.

I'm the second kind. I only explode when the simmering anger begins to boil. I know its not healthy, but it gives the anger a chance to subside and preserve the friendship. Of course if the anger is being fueled, then it will turn into fury. And thus, the delayed explosion.

So when people seem amazingly calm to you, don't always trust what you see on the surface, because you're not seeing everything.
