I had something vaguely similar happen to me.
We got called out of the line for a manual luggage inspection because, as a surprisingly bored security agent informed us, X-ray showed a knife of about a foot length in our luggage.
We had no idea what they were talking about.
We were half-way through unpacking the whole pack when my SO lit up and asked “could it be my ice skates?”
Agent took a look at the X-ray, nods, and lets us pack it back up without any further checking.
Overall, turned out harmlessly, but the sheer confusion of where that supposed knife had come from, combined with how blasé that security person was about the whole affair from start to finish stuck in my mind.
This isn’t about guys’n’gals.
This is simpky about how people work:
If your peers (friends, colleagues, family) have an opinion (any opinion), their default expectation is that you share that opinion - this is what being a peer is mostly about.
You can demonstrate solidarity by agreeing - this is virtually always the safe option.
You can demonstrate backbone by disagreeing - this can generate respect or animosity.
You can refuse to weigh in - this is mostly a middle ground between the two above.
How it actual shakes out in reality will depend on a myriad of factors, many of which you’re not even consciously aware of.
Thus, this random internet stranger can give you only three pieces of advice:
Trust your instincts on how to handle this. Your subconscious is very well wired to navigate social situations as best as possible.
If you ever change your opinion or “change your opinion”, announce it clearly and give/make up a reason. People disrespect people who are inconsistent, but they respect people who can admit to mistakes / learn.
Sometimes, you can’t win. Sometimes, someone will be pissed off, no matter what you do. It’s no fault of yours, some situations are just not salvageable to begin with.
