To not be a native English speaker.
My natural first language is Welsh. I went to an English university and obviously have a native proficiency in English but when chatting im more comfortable in Welsh.
So... I'm on a train in the Midlands with a friend. Had a chatty conversation with the conducter in English, guy sitting across from us very friendly. The we switched to Welsh and the difference in attitude was immediate. Felt very hostile. Very hard to explain, but as soon as we switched languages it became almost threatening?
I'm used to speaking Welsh in maybe more border towns (mainly chester) where its quite common, but thinking about it not in 'deep' England :) 😀
We keep going over it, but the change in attitude was definitely when we changed language. Is this really the experienced of non-English speakers? The hostility really was quite overt
