My senior year of college, I emailed a Danish/Swedish professor (had lived in both countries and published in both languages) about a niche research article he had published that I was unable to find. He not only sent me the article, but mailed a couple copies of his books to me in the US. Sadly, my Scandinavian reading comprehension has plummeted since then and I am unable to read his books anymore, but they sit on my shelf and remind me of that period of my life and my wonderful Nordic Studies professors.
