@KZO, even if she stated herself to be, I'm not sure I'd really call her openminded. It feels really uncomfortable to be approached by someone you barely talked to in high school, who speaks so insensitively about about something so... personal.
Not to mention that just because she's speaking in a 'friendly' way doesn't mean she's really being friendly. I'm not sure how to explain it, but there's this way bullies try to get to you, by acting overly friendly and laughing at you in your face, pretending that they're just really interested in you. Maybe she's just insensitive and dense and doesn't mean it that way, but the way she talked to Landlady really got me feeling really uncomfortable and on my guard.
