Moments of Happiness
They're almost always unexpected and go by too quickly. You don't realize them until they've passed, but everyone has those moments that, in retrospect, they realize they experienced true happiness. I'm quite lucky in that I've experienced many such moments, but here's one that comes to me:
Driving from Wilkes-Barre, PA to Baltimore, MD with my sister Ann and my niece Lowery. We had a cassette of Jesus Christ, Superstar playing on the car stereo, and Ann and I sang along with the entire album while on the road. Ann can sing, I can not.
I smile involuntarily every time I think about it.
