Things I have learnt

• "Oh Danny Boy" should always be sung in a resounding baritone. If your chin isn't touching your chest, you're not giving it enough welly.

• Contrary to what the other four families think, it is perfectly possible to reach Cornwall by lunchtime.

• It's not just a piece of driftwood, it's a time, or a place. It's somebody's big day. It's a day out on the boat with your friends, who feel younger with the smell of salt in their hair.

• Groups of men are generally eager to demonstrate their superior general knowledge by raising the volume of their voice. You can afford to speak quietly though, if you're the one who actually understands what goes on at the CERN nuclear physics centre.

• Childhood is generally better if your dad isn't the only one you know with a big moustache.

• If you grow up thinking that someone is just about the cleverest person you know, when they tell you that they are impressed with the adult you have become, you glow with pride.

We all loved you Keith, and you will be missed.
