Is it normal to know everything about a person but not their last name?
Is it normal to know everything about a person but not know thier last name? This kind of happens a lot with me. I can know everything from a person birthday, to address, to parents, to fav hobbies, fav color, fav food but I have no idea what the persons last name is. Is it really super significant to know a persons last name? I do in some cases but only if I have to differentiate them from someone else. Like if I know 3 johns. I know John Lee, John Ramirez, and john Sanchez.
