Things that have made my heart skip a beat:

I almost called this "the first time," but there's more to it then that. I was feeling pretty good on the way into work last night, and composed this with some joy in my heart, for no particular reason.

Things that have made my heart skip a beat:

As a child, thinking that the next day was my birthday.
As a child, puppies and kittens and baby critters. Being offered to see a monkey.
Waking up on the first day of school.
Riding my bike off the ramp we made over Tonka trucks.

Christmas morn.
Going to Six Flags as a child.
My first bicycle.
My first 10-speed.
My first ride on a 2-stroke dirt motorcycle.
My first airplane ride.
My first airplane ride in a light plane. (And most since.)
Mountains.
Tremendous heights.
My first kiss from a girl not a relative.
My first romantic kiss from any lady thereafter.
The first time I told a girl I loved her.
The first time a girl said it to me.
The dentist office waiting room-- entering, and returning from within.
Mail for me, as a kid.
Mail for me from a friend, all my life.
Compliments from someone I admire.

Hearing the dispatcher rattle off the ten-code that the subject I was out with was wanted, had criminal history, and had an assaultive history.
Waking up after having overslept.
Drawing down on a human being.
Having a door that I supposed was locked open suddenly.
Blowouts.
Daughters' screams.
Cries for help.

Being accused.
Chewing on foil accidentally.
Gunfire where I thought there would be none.

Loss of traction.

Add 'em all up with the others I've not listed, and I'm probably owed a day back, somewhere along the line.
