I did these for my last relationship. My ex and I broke up 7 months ago but I still knew 37 things. The only things that I didn’t know were his parent’s ages because he didn’t remember what year they were born or how old they were for the whole 2 years we dated (despite my parents even meeting them this never really came up). We also both lived in a city so we never paid attention to when trash collection happened because in an apartment building it is never a big issues. And he didn’t have one specific color toothbrush because he’d buy a cheap 4 pack and use a fresh one all the time. He also lived with his parents for a while and in a dorm so I guess his rent was non-existent but I answered that I didn’t know. And I never heard him listen to the radio. When he drove he hated the radio. It was usually defaulted to NPR from his parents. And I never did know his salary the entire time we dated because it wasn’t my business. I just can say he was getting by fine.
