Change is inevitable
They say
But this is questionable
I dare say

Past, present, future
had, is, might
a certain change of words
yes you will see

In past there exists an -ed
Add this and it'll be history

The present presents us with -ing
Add this and it'll be a present thing

To the future that is a mystery
You need to add a certain uncertainty
Might, Could, Would it can be

But change is not for me
The past, the present, the future
Is just but mere words for me
I have something that'll never change for sure

Now I will tell you
I have not loved
I do not love
I will not love
Anyone but you
And this was
this is
this will
Always be true

I have loved you
I love you
and I won't let a concept of mystery change that
for the future is just a change in time
And my love for you is already defined
My love is not a function of time
So it will never changed by times
So my love will always be for you

past, present, future participle might change
but still it will always be you
I tell you that's true

I told you
I am telling you
I will tell you
I love you
