My missus is a native speaker from Lewis and I did a learner’s O Grade back in the day (no Granny Danger jokes please). Also we had a week at Sabhal Mór Os***** a couple of years back, a learners course for me and a cultural type thingy for her.
My view is, no use forcing road signs etc on people in the wrong areas especially when they seem to just be made up half the time.
On the other hand, I’m somebody who believes every day is a school day. I used to be a teacher and tried to make the subject (maths) interesting by dropping in extra wee anecdotes, puzzles etc. You always got people who said “will this be in the test? Then why are we doing it?” You also got people who had a very fixed idea of what they would need in their future job, so completely dismissed anything different from that.
So when people say, what’s the point of Gaelic, I’m never going to speak it, etc, even though they live in a town like Inverness with Gaelic placenames, mountains etc all around them, or even Glasgow, and they’re not interested in even knowing the meaning of them, I think of those kids, except it’s adults saying it, and I despair.
