As far as actions in the past are concerned,
if you give the matter your attention,
you will recall various tenses:
the Past Continuous, the Past Definite,
the Imperfect, the Perfect, and the Pluperfect,
which we might call the more-than-Perfect;
we need not concern ourselves at the moment
with the Past Anterior.

I, at the moment, am not concerned with the past at all,
for you are very much Present, and your action
of brushing the hair from your cheek
requires all my attention.

Take, for example, this sentence –
“I was looking for a word, and found it
in a dictionary which I had.” You will notice
the action of looking for the word
extends over a period of time, and is Continuous.

What I notice is the luminosity of your skin
where the sunlight strikes your shoulder, for in my case
the action of looking at you is Continuous.

The action of finding the word is complete
and fixed in time,
and requires the Past Definite...

And I observe how beautifully complete you are,
and I am fixed in this moment
which is now and forever.

...while the action of possessing a dictionary,
in this sense, has no beginning and no end,
leading us to the Past Imperfect.

Your eyes, at which I continue to gaze,
are more than Perfect, having depths in them
which seem to lead towards an Indefinite Future.
And the Past Anterior and the rest of them
do not concern me at all,
for you see me looking at you,
and the corners of your eyes crinkle
as you smile at me, and in my case
the action of being in love with you
has no beginning and no end.
