My mother finally went to work as a cook and left me and my brother alone in the flat each day with a loaf of bread and a pot of tea. When she returned at evening she would be tired and sometimes dispirited and would cry a lot. Sometimes, when she was in despair, she would call us to her and talk to us for hours, telling us that we now had no father, that our lives would be different from those of other children, that we must learn as soon as possible to take care of ourselves, to dress ourselves, to prepare our own food; that we must take upon ourselves the responsibility of the flat while she worked.

Which sentence best describes the biased way the author approaches this topic? boars = bacon. and gammon, chops, sausages and feel your salivary glands begin to tingle at the thought of your teeth sinking into that first tender mouthful, and you will be half way towards a sensible attitude towards these creatures. they’re pigs. porkers, hogs, swine, if you will. they dig up people’s gardens, occasionally attack their dogs, spread disease and generally cause a nuisance. in culinary terms, they’re no different to cows or sheep or any of the other feeble-minded, four-legged frolickers which, in various pasties, pies and other assorted pastry cases, end up on our steaming plates on a daily basis. low in fat but high in deliciousness, by eating a wild boar you aren’t depriving poor little peppa and george of a long-lost cousin, but rather reaffirming your god-given position at the top of the food chain. if a boar could eat you it would, thus i say we should return the favour with interest. so say no to the misty-eyed squealers and man up, tuck in and pig out!
