There are some spam issues in the comments, so I had to disable comment editing for a short time. It'll be back once the spam bots are gone. FYI... they leave a comment with "great" and then edit in the spam stuff later, to get around the filter.
(Very literal. Think of holding your hands under a small waterfall. NOT for figuratively holding someone down. Both "r-" and "dr-" are idiomatic, "dr-" just has the focus a little more on the stationary aspect. "her-" is not idiomatic at all.)
