A daily commuter, Alex Johns, of Ryde, asks: ''Are we becoming a nation of backpackers? It doesn't seem so long ago that city workers on buses and trains travelled light - women carried all they needed in a purse, and for men it was just a wallet and sometimes a briefcase. Now every second person is lugging an overstuffed backpack. I'm always tempted to ask: 'Why do you need all that stuff?''' Good question. So, all you encumbered commuters, are you willing to unburden yourselves and tell us what's in the backpacks? Another sign of the times. Rhona Stoloff, of Woollahra, reports: ''Passing a shop in Edgecliff Road recently, I noticed a sign saying 'Sorry we are open'.'' And John Boast, of Hunters Hill, informs us that a signpost in Bundanoon pointing to the Quest for Life Centre and the cemetery (Column8, yesterday) is out of date. He writes: ''The Quest for Life Centre has been dead for some time but the cemetery lives on.'' Rick Steedman's traveller's tale of ordering a flat white coffee in Canada but receiving a glass of chardonnay (Column8, yesterday) drew this response from Mike Millard, of Vancouver: ''Yep, a 'flat white' is unknown in Canadian Rosetta Stone coffee shops. And in Canada the prefix 'Tim' goes with the suffix 'bits', not 'Tams'.''

He may well be right, if the following contributions are anything to go by. ''One of my friends once told me I was 'digging myself into a corner'', writes Max Philipson, of Cremorne. ''I tell him now and then that he's 'backing himself into a hole', but my favourite is, 'I'll chew you up, spit you out, and throw away the key!' '' If mixed metaphors can be confusing, mixed drinks can be downright disgusting. Jennifer Saunders, of Bungendore, tells us: ''I ordered a lime and soda in a bar in Ireland and was given the most vile drink, which turned out to be lime and cider.'' An internet search by Aidan Wilson, of Bathurst Island, Northern Territory, of ''Googled'' as a verb (Column8, yesterday) yielded more than 20 million hits. And on the topic of genericised brand names, he tells us: ''In the outback, or more specifically in Kriol, the creole language of many top-end Aborigines, 'Toyota' has become the word for a four-wheel-drive, whether it's the Toyota brand or not. Any other car, whether a Toyota or not, is a 'modaga' (motorcar).'' It's bad news about one of the Sydney pigeons that stowed away on a container ship and ended up in Bluff, New Zealand (Column8, yesterday). Although most of the birds escaped, one was captured and is on death row. The Bluff Beacon's editor, Alan Mitchell, reports: ''The Ministry of Agriculture and Forestry has confirmed that the captured pigeon is being euthanased because of risk of avian disease.'' More likely revenge for the underarm bowling incident.
