A recent text exchange with my gf has really stumped me.

My gf and I were texting and she said she was going to the grocery store. I said “make sure you look both ways before crossing the street.” She said “oh wow, thank you! What a great idea, I don’t think I ever would have thought of that.” <br><br>I thought she was being sarcastic. Like, how do you not think of that in this situation? She texted back some things (copied below) to convince me that she wasn’t being sarcastic, but I’m stumped. <br><br>Her text: “I’m 100% serious. It’s not something I think of naturally. I think the only time I ever look crosswalks are when I’m walking with my boyfriend, who I love very much and don’t want to die. Because he’s always like “make sure you look both ways!” It’s actually starting to become an internalized habit for me because of how often you tell me to do it, but it’s not something that I’m naturally inclined towards doing.” <br><br>I do live in a city with no crosswalks and bad drivers. But I don’t think that’s enough to explain her comment. She’s also very intelligent and a well educated college graduate. I’m stumped. Is she being sarcastic? Can a person really be this obtuse? Can someone explain to me whether there is a philosophical underpinning to this comment and what she meant by this? Or is this something that I need to address with her?<br><br>Edit: I’m a bit flabbergasted at the number of replies here, but there was one thing that I thought was worth mentioning. She is from a super wealthy family, and has never had a job. So she has a driver at her disposal 24/7. So basically whenever she goes anywhere she is driven by a driver and doesn’t need to walk. So that’s why this isn’t in her consciousness.
