I’d describe it as helpful. You can accept help and your writing will improve. You do well enough, I accept, but why are you afraid of doing better?
Just English. I’ve travelled the world and can order a beer, food and a taxi back to the ship in lots of languages but English seems to work everywhere. Do you suggest I learn Norwegian? Or an Aboriginal language spoken by only two dozen people? I tried my schoolboy German in Germany years ago and was told to try English. Europeans have lots of useful options - a foreign language is spoken a couple of hours drive away. I’m in Perth and Sydney is as far away as Moscow from London and there’s only one language spoken throughout.
