I was having trouble making sense of all that Rosie was saying, doubtless due to the effects of the alcohol and her perfume. However, she had given me an opportunity to keep the conversation on safe ground. The inheritance of common genetically influenced traits such as eye colour is more complex than is generally understood, and I was confident that I could speak on the topic for long enough to occupy the remainder of our journey. But I realised that this was a defensive action and impolite to Rosie who had risked considerable embarrassment and damage to her relationship with Stefan for my benefit.
