Husband used to play bridge at home with his father and brothers, and he persuaded me to join him. I had played before, but not much.
We used to belong to clubs, but he was much better than me, I just couldn't take it seriously. It's best if you have a regular partner though, you work out your own bidding system.
When we moved to France we joined a club - really enjoyed it, but they're so late finishing (sometimes small hours of the morning) and then the long drive home in the dark, we stopped going.
As Mum... above says it's very addictive.
