Dogged Nice Guy/Headscratchers


 * For the most part, I like this trope. When well written, it works and is easy to relate to. The one time it doesn't do it for me is when someone is a Dogged Nice Guy (or Girl) for a person who has no respect for him/her. Quite a few examples of this exist. It's one thing to have this for a person who sees you as either just a platonic relationship or you're just to shy to approach, but I don't see why anyone would have feelings for someone who treated him/her like dirt.
 * There's actually some Truth in Television for this trope. Some people are insecure enough that they accept that kind of abuse and feel that they can win the person over or worse yet, they desire it. It's not as funny in real life, though.
