in common usage of speech,
words and phrases are
sometimes seen to behave
almost as do
punctuation marks
in writing,
for example and
for instance, it will be taken
for granted that we
will grant you
phrases

such as: as such
and such; and such as                                
but if (and only if)
such there be; and
such being the case,
we go on, like so:

and so on,
and so forth,


and whatnot,
and what have you,
and what's more
and moreover
and furthermore

...

a bit of
investigation
we find
ourselves in
a state
whereby
we are rendered
utterly baffled;
thereby and thereupon
we feel our efforts to
have been an
exercise in futility.

therefore...

we resign.
