Imagine: "Poorman". I mean, come on. Nobody should be named "Poorman" for any reason.
All your life, you'd have to be filling out your name somewhere - any place that needs your name and address.
"Laura Poorman, 123 Anywhere Street . . . . . . . "
And then, some time down the road:
"Thank you, Ms., uh, Poorman, we'll be contacting you. . . " (Ms. Poorman?)
