Many years ago, in the first lesson of one class at high school, we did an ‘introduce yourself’ activity which consisted of saying “My name’s [name] and I like [food starting with that letter]”. The first D in the class (I can’t remember his name) said “I like duck”. The second (Debbie) said “I like dates”, which provoked a few light-hearted comments. When it was my term, I couldn’t think of any other food beginning with D. The teacher finally suggested dill pickles. Some of my classmates started calling me that as a nickname, but fortunately I changed class soon after, for unrelated reasons.
I am now teaching English again part-time, and the first lesson in the textbook was about food. In one lesson I did a similar activity in which students say “I went to the market and bought an apple, a banana etc …” through the alphabetic (vocabulary, pronunciation, countable and uncountable nouns etc). Duck was one of the items in the vocabulary list, so I was expecting the student whose turn it was to say that, but instead she said …doughnuts.
