Earlier this season I had a hamstring niggle. While Lee considered this a "niggle", Rattray praised its brevity. He has been the constant niggle in the conscience. Niggle has other pressing work duties as well that require his attention. Then Niggle himself catches a chill doing errands for Parish in the rain. Leeds had decided to niggle at Liverpool, and in particular Keegan, in the match. Like Niggle, Tolkien came to abandon other projects or graft them onto his "Tree", Middle-earth. Shippey points out, however, that "Leaf by Niggle" "quite certainly" was an allegory. Eventually, Niggle is forced to take his trip, and cannot get out of it.
