If you asked me the same question five years ago, the answer would be entirely different. Likely something along the lines of: "It depends."
But today, if the person I was talking to was spouting absolute fiction, I'd probably call them out on it. Whether you're my elder, my professor, my boss, my parent, I don't care. The only exception I can really think of is perhaps delaying the confrontation. For example, if we're in a meeting and you lie to my face (and I don't think you really mean ill will) I may confront you afterward to avoid the drama.
I used to hate confrontation. Not saying I'm a fan now (it's still anxiety-inducing), but I remember having such a difficult time with those tough conversations. I'm not really sure what changed - maybe this is just a part of growing up - but I don't really think twice about speaking out or up anymore.
When I saw this prompt, I immediately thought of the Parkland teen survivors who have remained steadfast in their beliefs and goals and taken absolutely no bullshit from anyone, no matter their authority. I wish I had been more like that at 16.
The #100daychallenge writing series is my way of holding my right brain accountable for all the brain fog in hopes that I'll learn to creatively organize my thoughts and learn something(s) new about myself in the process. The challenge includes prompts from the San Francisco Writers' Grotto's 642 Things to Write About. You can also follow my #100daychallenge here.
