1. Public transport stops:
Why have people decided the benches on train, tram or bus stops are for putting their shopping, school bag, boxes on, rather than for people to sit on? It's not cool, people, especially when the other people at the stop are older, injured, pregnant or infirm. Your stuff is not as important as that human being right in front of you. Honestly.
Also, smokers. I've said it before, but its important to move downwind of the stop when you smoke. It's nice that you're considerate and move away from the people, but pointless if you move upwind. I'm starting to think its some passive-aggressive pay back at the non-smoking majority.
2. Climate Change:
Truth is the first casualty in war. When any public debate becomes as heated and politicized as this one is, it triggers my deepest distrust. I count as friends passionate believers on both sides of the 'debate'. The thing I notice about their - endless and not always friendly - debates is that no-one ever alters their opinion by a millimeter, and they quote different authorities. I also notice that all of them recycle (for example), so their differences are basically rhetorical rather than behavioural. I doubt the Carbon Tax will either save or destroy the world as we know it. But hey, I could be wrong.
3. Children and Recreational Shopping:
They don't really mix. First of all, it's too noisy and stimulating for most kids after, oh, about 30 minutes. There's nothing for them to DO. You're not going to approve of them touching everything and you're not going to buy everything they want, are you? (I really hope you're not.) Little kids are strapped into strollers where all they see are legs. And guess what, big kids know that no matter how often you say, "yes, in a minute" they're here for a good two to four hours.
Recreational shopping with other adults barely works. Someone is always being patient, or failing to be patient, with the other person's interest. Witness men in women's clothes shops and women in the software/war/railway/car section of the bookstore (ok, cheap shot and stereotypical but you get the idea). An adult shopping companion won't ususally sigh loudly, demand food, cry, or run off the minute they're bored, but if you people watch you'll see plenty who want to. Adults are socialised, children aren't.
So shop by all means, but don't imagine that it is a good family outing, or a treat for the kids. Unless you're going to spend a lot of money on things they don't need and only want for the next 48 hours, then coming home with your loot via a fast food outlet where they can load up on food with no nutritional value and lots of E numbers.
