It must go without anything following for it to count.

It must be an accident that makes you want to cry.

I’m not picky, but my favorite kind is when it comes with a history.

The kind of eye contact that only lasts .5 milliseconds but somehow replays everything you did with that person.

A montage of what will from now on go

unspoken.

A quick trip

gone in the blink of any eye,

literally. 

For a moment you are all the other person sees. Just you.

They can go on to shift their gaze south,

west, southwest, northeast,

but for that one moment in time you were theirs.

My favorite is the kind that makes you have a cheeky smile.

A pinkened cheek

A sudden vomit in your throat.

The kind that reflexively brings your hand up to smack yourself in the face because you're sure your hair was messed up or you had something in your teeth.

Sure, “Eyes are the window to the soul” but

personally I’ve come to think of eyes as marbles. 

They continuously rotate, slip, accelerate,

and only pause for a reason.

I simply love being the reason your marbles pause.
