Speaking of the devil herself. Posts and is gone in 60 seconds. Give her 90 more seconds and she'll log back in. Do a drive-by and log out just as quickly.
Some of us have to post that way, as we are in the many stages of preparing for work, e.g., bathing, shampooing, posting, dental hygiene practices, posting, dressing, posting, taking care of the cat's needs, posting, breakfast, posting. It is a "time" issue. I've logged back in and out, too, as sometimes I lose the tab to this site, while searching other sites....
And other times, not caring enough about a response to our posts to go back and notice.
You get the picture. We're all here for different reasons, and do what it takes to enjoy the journey.
