You're quite right, Stanley, I suppose, that people only read the sign-off line once or twice and then ignore it. This is the first time I've read your sign-off and so it struck me with the usual initial blast of Tolkien literary gun-powder. I expect repeated readings would deprive it of its effect.
In fact, I have been finding it rather unsettling in church now that we memorize Bible passages as a congregation. Our Pastor wants us to commt Bible passages to memory should we ever become blind or deprived of Scripture. It seems ilke a good idea, but week after week, chanting the same verses -- the earlier verses in a passage becoming more and more familiar with the more frequent repetition -- seems rather to weaken the overall effect of the words, rather than strengthen them as one might expect.
