i think it has more to do with dialect than anything. i speak appalachian dialect so sometimes i’ll use an archaic word. the irony is she usually figures it out faster than most other english speakers since our archaics are largely eastern european in origin, but to her in that moment it feels like “oh, i don’t know what this native english speaker is saying, i guess english is still a skill i’m working on”
i always am like “oh no, i talk funny” but it’s been happening more as she’s become closer friends with me and my fiance and we all talk on metaphysics and shit
be patient. read thoroughly. be open to a learning experience
