As I'm usually in somebody else's house . . . I'm a professional guest really . . .the pattern of my Sunday is dictated by whoever I'm staying with. Wherever you are you have to judge what the rules are. In some houses, breakfast might go on all morning, in others everything might have been cleared away by 10. And in some places it's okay to come down in your dressing gown whereas in others it most definitely is not.

If my hosts are churchgoers, like my great friends the Montgomerys in Co Down, then I'll be up and dressed for the walk to church. I'll have remembered to pack a good suit and will bellow out the hymns from the front pew.

The benefit of this virtuous activity is that you feel entitled to that pre-lunch drink when you get back to the house. Fitting in with the form is the way to ensure you get asked again.

After years of practice, I'm a good guest and good guests always leave after lunch. One of my great pleasures is being at home on Sunday evening, pottering around and getting ready for the week ahead. One feature of my Sunday evening is that I always write my thank-you letters for the week gone by so that they're ready to be popped into the post first thing on Monday morning.

Of course, being a judge on Celebrity Jigs 'N' Reels has disrupted the pattern of my Sundays in recent weeks.

Last Sunday I had to get up early and drive from a big house party in east Cork to be in Ardmore Studios in Bray for rehearsals at lunchtime. Because the show goes out live, and the show is complicated in terms of all the various elements, the rehearsals are quite intensive.

The programme goes out live between 6.30 and 7.30 and then there's a lot of hanging around eating chocolate biscuits while the votes are coming in. I use the time to write my thank you letters. George Hook and I tend to hang out together in our dressing room and solve a few of the world's problems. Colin Dunne and Jean Butler resolve the world's dance problems. If friends are in the audience then I go and say hello to them in the bar.

Children love coming because they get to eat crisps and Coke. If George and I look slightly queasy when the results part of the show goes out it's probably because of a surfeit of chocolate biscuits rather than a reaction to the dancing or the vote. A digestive too far, you might say.

Once the show is finished I jump in the car and drive straight back to Co Meath and my bed.
