Discuss images from the past
Find images from past events, celebrities, sport championships and people that used to be in the media. Try to not make it into a quiz. Instead of saying: Do you remember where this is from? Another approach could be “I remember when Anisoara Cușmir-Stanciu won the gold medal in the Olympics in Los Angeles, what a magnificent jump!” / “I remember when Heike Gabriela Drechsler won the gold medal in the Olympics in Barcelona, what a magnificent jump!” Using the pictures can guide the conversation and keep it going. However, associations and digressions are welcomed, you don’t need to strictly stick to the pictures.
