But here's the deal: I know by now that the damaged ones are the most dangerous because they think it's their god given right (by virtue of past pain) to be a bastard to those who care. Once-upon-a-time when they were young and naive, they would undoubtedly have made perfect partners. But then life happened to them and now they really couldn't give less of a shit about how much you're willing to give them. In fact, taking is what they do best. They're amusing, and they're charming (when-they-want-to-be) but they're hardly potential for anything worthwhile.
Even then, I'd still go for the damaged ones. Textbook case of masochism I be.
