You make one tiny mistake … Nigel Hancock of Castle Hill left open the window of his wife's car. It rained overnight and made the driver's seat wet. He writes: "Thus, I was required to chauffeur her around until the excess moisture had been absorbed by towels and my denim jeans." This has made him the butt of jokes. "My kids now call me Squarebob Spongepants."

Some call it progress, but several respondents are mourning the passing of the handwritten Bondi Beach lifesaving whiteboard. Gee Smith writes: "It's just not the same. No more little messages and smiley faces."

Film critic Annette Shun Wah was reading the IF (Inside Film) Awards newsletter. "I was … proud to discover that Australian awards shows can provide something even Hollywood might find difficult to match," she writes. The newsletter states the Presenter Pack includes goodies such as cosmetics, DVDs, and magazine subscriptions, and adds: "Dinosaur Designs (who are responsible for creating the IF Awards trophies) are adding a set of bowels." You never know when you need a spare set, Annette.

Fair exchange? We know the Kiwi dollar is a poor cousin but Ian Nicolson of Banora Point is amazed at how poor. When he went to change a New Zealand $20 note at Westpac he was told he would get just $8 after fees were deducted. The only place to change it without a fee was a casino, he was advised.

Why does the Harbour Tunnel have north/south signs every 100 metres? (Column 8, yesterday). Stuart Greaves of Pymble says it is in case you break down and cannot remember whether you were going to the CBD or returning home. He adds: "It's the same reason they make lunchboxes with clear plastic lids - so people know whether they're going to work or going home."

Greg Nash is not the only person to support krill in their losing struggle against terrible whales (Column 8, yesterday). Carl Clifford of Gorokan says British parodist Les Barker has a song, entitled Krill, which bewails the plight of the tiny sea creatures and complains about whales getting all the good publicity. Barker's songs include treasures such as: Up the Creek without a Poodle, Gnus and Roses, and The Sloop John A. Surely he could have found a better title for the krill song? We offer The Krilling Fields, A View To A Krill, or Free Krilly.

Do bogong moths make good compost, asks Catherine Craddock of Hornsby. She climbed five flights of stairs in a city building and estimated there were a hundred dead bogongs per flight. She writes: "It had me wondering, if you swept your way down in a few city high-rises, could you earn a quid selling the resulting pile to a gardener?"
