For about 40 years, my father taught history at Loyola College in Baltimore. At his retirement party a couple of years ago, my dad's colleagues roasted him, saying he's the only person they'd ever met who would stop at every historical marker along the highway, reading every word on it before getting back into his car and driving on. This blew my mind. I'd spent my entire life assuming that this was what every historian did. No. Just my dad. He's such a historian that other historians make fun of him for being a historian.
