Littlest spider

Not being afraid of spiders in the least (had a pet Tarantula named Harry as a kid), I've had a lovely afternoon with a small one. S/he's been hanging about exploring my monitor. Smooth black with several bands of white on the abdomen that look a bit like a smile when the spider is inverted. I have no idea what kind of spider this is, but I've been charmed by it for several hours now. Can't seem to find its distinctive markers on any site (yes, I know they aren't really identifiable in that manner), so I'm giving my little friend complete respect and distance.

I'm paying attention, little one.

Are you being served?

So you've finally decided to come visit the Tryst Inn, most likely on your way to somewhere else. We're sitting around chatting in the living room or back porch, the time is perfect for a couple of drinks.

So what drink do I serve you?
