Punctuation and Capitalization: a true sign

Do you know how I can tell?

It's quite simple really-
Everything changes.

There is distance in your words,
Pauses instead of phrases,
Less feeling, more statement,
And possibly the most obvious of all...
Punctuation and capitalization.

What once was only
no, its cool
Now becomes the more proper
No really, it's fine.

The only thing truly hard to see-
What the issue actually is.

I can easily assume
The cause came just before.
But that would be--assuming.
And world knows
I could be wrong.

Of course you will not tell.
At least not for now.
For now it is more proper.
And I just hope you know I love you.
