Of course, I was not always right. I questioned the value of Crossrail (a scheme revived by Prescott after being scrapped by the Conservatives), suggesting wrongly that it may be "doomed to hit the buffers" […]. A dozen years later, I published my book on it, extolling the line's wonders. We are all allowed to change our minds. 2024 January 10, Christian Wolmar, “A time for change? ... just as it was back in issue 262”, in RAIL, number 1000, page 61:

An utterly emphatic 5-0 victory was ultimately capped by two wonder strikes in the last two minutes from Aston Villa midfielder Gary Gardner. Before that, England had utterly dominated to take another purposeful stride towards the 2013 European Championship in Israel. They have already established a five-point buffer at the top of Group Eight. 2011 November 10, Jeremy Wilson, “England Under 21 5 Iceland Under 21 0: match report”, in Telegraph:

Here, too, are Boots and Brewer, and the two other Buffers; each Buffer with a flower in his button-hole, his hair curled, and his gloves buttoned on tight, apparently come prepared, if anything had happened to the bridegroom, to be married instantly. 1864-1865, Charles Dickens, “Book The First, chapter 10 "A Marriage Contract"”, in Our Mutual Friend, archived from the original on 06 Jan 2014:
