It'll entirely depend on whether or not I'm feeling the guy. If some random guy asks me out, and I don't even know who he is, I'm gonna say no, unless he's Daniel Henney/Takeshi Kaneshiro/Jude Law (swoooooon!) I've got to be attracted to the guy. If I'm not attracted to him, it doesn't matter how great his personality is... it ain't gonna work. I suspect that I have ADHD, so the guy has to have knowledge in various things to be able to keep my interest... in other words, be able to carry on a conversation.
