But wedding lists should be to help couples build their first homes together. Oh please, that doesn’t happen any more. Say your best friend announced that they were getting married to someone who they didn’t already live with. How would you react?

I’d try to talk them out of it. Exactly. Everyone who gets married these days already shares a home, so the last thing they need is a duvet set or crockery.

But they’ll always need toilet paper. Well, and other stuff. The thinking behind the Tesco wedding list is that it’s much more practical to help a newly married couple out with their weekly shop.

It's rather nuts that in just 20 years, premarital cohabitation has gone from somewhat fringe to expected. Of course, housing costs may have something to do with that.
