While dropping me to school for the very first time (the family car was “WBD 2987”), my parents made me repeat the following sentence several times (although illiterate, I could count): “My telephone number is 472784 and my grandparents’ number is 442740”. Half a century later, I remember those defunct numbers. But I have no clue what my current landline is. I have trouble recalling my cell #, though I have had it for 19 years. I have come close to being arrested once because I couldn’t recall my car number offhand.
