I have to agree... there are absolutely shades of gray. I've always had a personal policy of if you ask someone out, and they decline, give it a while, then ask a second time, in case of a timing issue, then never bring it up again.

Though, I'm not one to force myself onto someone like that, we all have feelings, emotions and desires. It's not always easy to read a given situation. And the those outlined in TFA are definitely over the line.
