Depends on how threatened I feel by the present circumstances. If I'm in an exposed position, with people all around me that I can't keep an eye on, and I don't the know or yet trust the person I'm talking to, then no, I'm not very good at talking. I tend to drop entire words out of sentences for no particular reason. Like, if I'm ordering a coffee, I'll say something like, "Can I get a large *blank* with two cream, please." And then people will have to ask me to repeat myself. And I sometimes don't catch what other people are saying because I'm too busy scanning the area for threats.
The less physically vulnerable I feel, and the better I know and trust the person I'm talking to, though, the better I am at communicating. I can be quite well-spoken and I'm always sensitive to social cues, so I find that once people get to know me they're much more likely to enjoy talking to me and start telling me all kinds of crazy things. That's usually when people discover I have a sense of humor, too. Which seems to catch people off-guard.
Beauty isn't everything. It's the only thing.
