Card clash

If you are using public transport in London, you can use an Oyster card or a contactless credit or debit card. Yes, you can also use mobile devices with eg Apple Pay.

You often see people putting their wallets directly onto the readers. If these contain more than one card that could be used to pay for travel, it is possible that the wrong card is chosen by the machine, or no card or all cards are used. This is the so-called card clash.

Do avoid it by carefully taking your card out before using it.


I have just come back from a holiday in Chicago. I have been there very many times, but always enjoy going again and always find new and rather surprising things to do.

It is a very special place. If you love your architecture then you will find plenty to enjoy. The boat trips down the river were really busy, and are worth doing.

It’s a great place for walking, and the food can be wonderful. Yes, sure there are the rubbish places, but there are some truly wonderful places, especially if you are a meat eater.

What sets the city apart are the people, who are genuinely friendly and polite. Given its size, it is a clean city too.

Definitely worth a visit, if you can. Don’t dismiss it as just another big city, because it isn’t. There’s a chance to see some fine theatre at reasonable prices, and the Navy Pier is one of the biggest attractions in the whole country.

The ‘expert’

I have grumbled about YouTube videos before. I am not interested in posted versions of plays, tv programmes or music, nor am I interested in postings about celebrities, fashion and all that stuff.

I quite like informative or helpful videos.

It’s great to see a video called, for example, “The top five features of X that you have never used.” You assume that the person is some kind of expert on the subject.

Then the video begins and it’s re-phrased. “Five useful features of X”.

There was one the other day that said “All the albums by Y from worst to best.” Almost the very first thing the presenter said was “this does not put these albums in order from worst to best.”


Anyway, the presenter is some kind of expert. I am listening to you because you have knowledge that I don’t.

There is one series by a nice Australian lady about Maths/Physics at university. She has made a large number of videos and seems to speak with some authority. And yet she has made a complaining video about how people see her as an expert. She doesn’t like it. They ask for advice or information, and she’s not happy about that.

Honestly, time to go elsewhere, I think.
