Many of the best wallers (like their walls) are exemplary, highly supportive and genuinely gracious. They are not mean spirited or coarse (even if their walls might be 'coursed')
A well built dry stone wall is not a high maintenance structure. It lasts for years. It doesn't need special attention or cause a lot of trouble. It's just the 'standard' thing you would expect from a wall or a person. It does the job well and leaves other things to sort themselves out over the natural course of time.
Oh that a waller's talent never exceeded the level of their character. Oh that highly talented wallers conducted themselves with as high a standard and as keen a concern for composure and integrity as their stonework seems to display.
