I still remember when I was a bachelor's student in Colombia and I wanted to attend a conference she was organizing. I could not make it to the conference but we had the most gorgeous discussions on The Little Prince, which was the book I would talk about. She always reminded me that I could go to Nigeria any time, and be welcome at her house. I actually had this in my bucket list somehow! My condolences to the family! Wonderful woman!
