Where I live people are less obsessed with wedding rings I guess... I've had people (co workers who've known me and husband for years ) suddenly say: 'You're married?'
I keep my ring on at all times. It's a narrow golden band on my ring finger. There have been times when I've been using that hand in .. ehm.. some sort of activity
with another guy and I looked at it and sort of smiled at the irony.
I'm proud of my marriage. I talk about my husband. Why would I not want to wear that ring? If a stranger approached me and was interested in me, I'd tell him soon enough that I am already in a relationship even if he did not notice the ring.
