Gangsta Granny by David Walliams

Ben, a curious boy, hates having to stay with his old Granny every Friday because his parents go to see a dancing show named “Strictly Come Dancing”. He finds it boring and repetitive as his Granny always feeds him cabbage-related dishes, most commonly cabbage soup and cabbage chocolate, and they are constantly playing Scrabble, plus her television hasn’t been working since the 1990s.
