I’m not sure if this is BPD related but is it normal that my opinion of people can drastically change in one interaction or even just seeing someone do something? For example I once had a 10 minute hypothetical conversation with a person talking about how I admire them because someone told me they didn’t like doing anything extracurricular, I’ve never had more than two uninteresting interactions with them and yet now I have a seemingly permanent good opinion of them for no good reason, or another example being a kid on my bus today coughed into his arm and I immediately liked him, to reiterate he did something most people do and just because I liked it for a second I now like him even if I never meet him for real. This goes both ways too, there’s a guy in my English class who I’m about to pick a fight with because he’s been an obnoxious prick twice.

To summarize is it normal that my opinion of people can change so fast?
