Irritating mannerisms

My blogmaster has made what I admit is a valid point. He says I use too many 'of courses', and 'howevers' and 'appparentlys'. He's quite right, I admit it (see how adroitly I side-stepped that one!). I shall try very hard to do without them, and it won't be easy, for they operate as a kind of comfort blanket (like chewing a pencil end, or lighting a cigarette), in times of particular narrative stress. To those who might already have offended by them I apologise - they shall henceforth be eradicated, one by one, at source.
