Alan and Emily, who were brother and sister, were having a discussion about their favourite types of food. ‘I seriously just don’t understand how somebody cannot like chocolate cake’, said Alan. ‘I just don’t understand how people can like it!’, exclaimed Emily. ‘It’s just disgusting.’ Then it was time for the drinks. ‘I mean, it has to be Fanta’, announced Emily. ‘Are you crazy?’, asked Alan, bemused. ‘Coke is absolutely, by a mile, the best without question.’ Next, it was the spreads. ‘Nutella is good but you like marmalade like me, don’t you?’, asked Emily. ‘No’, he said. ‘I like Marmite’. ‘That is revolting’, revealed Emily. ‘I do like Marmite and marmalade mixed together though,’ she said.
