Let me see your anecdote with another, growing up in Scotland I had the exact opposite experience.

Depending on the area and interaction, you'll find Scots. Formal encounters are most certainly conducted in English with the odd Scots word thrown in however in my experience, particularly when concerned with community work, Scots was more common than not. On a lighter note, I recall visiting a comic theatre production in Arbroath which to my surprise was mostly spoken in Doric, and found myself odd one out and missing many of the jokes.

Regarding education, in high school we had entire units where we read and wrote Scots, and the majority of classroom discourse took place in Scots. This was not a special language nor otherwise remarkable school in any sense, it just seemed to be par of the curriculum in Angus at the very least.
