I have a relative like that. We lived together for about a year. When I noticed how I’d ask how her day had gone and she’d give a blow-by-blow, but never ask about my day, I experimented with her a few times just to make sure that I wasn’t mistaken and then added it to the growing list of oddities I’d observed about her. Eventually it all boiled down to the simple fact that she is a selfish and self-serving woman. She doesn’t ask about anyone’s day because it has nothing to do with her. And she doesn’t realize how rude it is because her head is too far up her own ass. She can’t even see it. Needless to say, she’s on the list of people who I keep at arm’s length.
