My ex-husband..lord..lord..lord! He was English. Our first date lasted many hours because he had to say everything twice. I am still not sure what a “niggle” is. The best I can figure out it is a slight pain, but I wouldn’t bet my life on that being a precise definition. All in all, he was a pretty good guy if he could have just stayed dressed and out of bed with EVERY beautiful woman he saw orat least most of them.
