are you engaged?

I've written a column about wearing a ring on your finger if you're married, due to an unfortunate experience in a dance class that caused me a lot of embarrassment. But I think there should be some kind of protocol for guys who are engaged. Girls have that huge rock on their hand that shouts "TAKEN." But what about guys? What about guys who seem interested in you and therefore you become interested in them, only to find out that they're engaged?

Guys, at least mention your fiance in conversation if you're about to get married. You're about to make the biggest decision of your life. It's exciting and wonderful! So let people know about it. Don't pretend you're available if you're not, and save someone an embarrassing moment or a shock when they find out you get hitched in a week...or, you know, the next month.
