What is an interesting story about Adam smith?

One interesting story about Adam Smith, the father of modern economics, involves his time at the University of Glasgow, where he was a professor. During his lectures, he was known to become so engrossed in his thoughts that he would often forget his audience, speaking to himself rather than the students. This quirk led to a memorable incident when a student, trying to engage him, shouted out a question, prompting Smith to respond as if he were conversing with an imaginary friend, illustrating both his genius and his eccentricity.
