Just realised this makes it sound like we have never been invited to a friends for dinner before
We have a small circle of friends, all of whom are happy to get together for a take away or a plain and simple spag bol/lasagne etc so no real cooking involved. However, this friend is a fantastic cook, and I wouldn't dream of inviting them back for a take away or a spag bol.
Also our other friends we have known for years, but I am too embarrassed about my lounge and dining room to invite anyone new round nowadays, especially when I think of the beautiful house this couple live in. Think grand designs
One further thought I think there might be two other couples invited, does that make a difference?
