What's in a ring?

It's very exciting to be engaged and I absolutely love my beautiful ring. And there's the rub. I'm still very much getting used to having it on and I adore the sparkliness. But I've watched enough newly engaged girls make a big deal of flashing around their new rock and hate the habit, that I've become completely self-conscious about my own left hand. I don't want to be that girl, so I find myself consciously hiding my left hand. I wonder when I'll grow out of that...
