OlderNoWiser when I was being interviewed for a teaching job at a local college I was told English is a difficult language to learn and it was a huge advantage to speak English.
I taught many adults whose first language was not English and they all thought the same. Foreign students always wanted to speak English to get practice with 'natural' English speakers. Perhaps now it's easier for children to learn English than adults because of TV, the Internet and social media. So much is in English that we don't give a second thought to. Even if you Google a page and it is not in English, press the button and it's translated for you.
I don't like seeing flags in gardens either, unless it's to do with a sporting event or something like that. In my area the BNP fielded a candidate at the last election, so some will support that party. They lost their deposit, but it is still significant change in the local community. I am not keen on seeing flags as I perceive them as signalling support for parties like the BNP and UKIP.
I do like the idea of a red dragon in the centre of the Union Jack. Wales should have its own representation. When I've seen the Welsh flag flying in Wales, a lot of the time the Union Jack is next to it.
