We had an interesting conversation. She had completed a PhD in Greek literature, I think. Self-funded. Taken the standard time. She was sorry about all the domestic responsibilities she had put on her husband. She had, with her, a younger friend (a lady probably late 50s, early 60s) to help her with computers :D
Made me feel very differently about all the hard work I had done. Very inspiring and uplifting. She said, she did it because she was bored and wanted to go beyond her two Masters degrees.
