Oh, and I have to mention one lady who does all of my book covers in cross stitch and frames them. Muriel. She's amazing. I just received one for my latest, Love And Dr Devon, actually. It's very sweet of her to do it.

I get up to 400 letters a week, so I have a full-time PA, but I try to answer everything. People don't seem to realise that if they send something living in the post it's going to die on the way. Especially when you wrap it in a polythene bag.

At school I was called Fred, which is my middle name. At that time, Fred was considered to be a bit of a horrible name, so that's why. Otherwise, I was called Titchy because I was little. I was still only about 4ft something when I left school. I grew a foot under glass in my first year as a gardener. It's really quite amazing what sun and manure can do.

Airports - they're not my idea of fun at all. Some of the staff are lovely, but you do always get one or two that seem to forget that it's actually costing you a lot of money to be there and be insulted by their surliness. Times have obviously changed and we need to get used to being more strictly vetted, but they could be more pleasant about it. A smile wouldn't go amiss.

I get nice letters, but really I have no idea. I just try to enthuse people. You've been married for 31 years.

Always take much less than you think you'll need.

I don't like people being rude. Bad manners and arrogance make me cross. People making others feel uncomfortable. And I really don't like it in restaurants when people are rude or patronising to waiters. I feel like saying, 'They're not your slave'. But my knees only shake around once every five years. You're safe, don't worry.
