A kiss is a sentence
it may run-on and on and...
stop, step off, take a breath.

A kiss is complex
if you're young or inexperienced;
but not to worry;
with time, it's enigmatic.

A kiss is compounded,
when confounded and complex:
and should you try expounding it;
your kiss may lead to ***.

A kiss that is declarative
is indicative not imperative.

A kiss can be inverted;
that's diverted, not perverted.
(or vice versa)

A kiss is exclamatory,
As in, "Not now!"    "I'm sorry!"

A kiss is.
A fragment of a kiss.
At osculum interrupta.

When is a kiss too questionable?
When it's probing, or incredible.

My advice.
Skip the semantics.
Don't parse stars and moon.
Just
Keep It Simple Stupid
Full stop
(or not...)
