If a kid walks up to me and tries to practice their English, I'm totally down. Actually happens a lot in my neighbourhood, the kids around here know I'm friendly.
If I'm out and about and their mum pushes them to say hello, I'll be absolutely nice to the kids. And the parents too.
If an English teacher tries to rope me in to be their unpaid mobile class assistant, that teach will get told to fuck off in no uncertain terms (in a very polite tone and said quickly so the kids don't understand.)
I'm not down to assist a paid enterprise as a free resource.
