I used the word 'obsequious' in conversation with someone today and they asked me what it meant, I told them and they asked me where I learned that and for a moment I stumbled because I didn't immediately know the answer. Even now, hours later, I still can't answer definitively because I genuinely can't remember where I read or heard it for the first time. I'm not going to lie, I had a momentary existential crisis where I actually looked up the meaning to make sure I was right which was reassuring in the first instance but still left me feeling more than a little lost.
