So... second guessing someone's retelling of a completely sober, undoubtedly career impacting scenario (one way or another) in the workplace is equivalent to second guessing someone's retelling of a drunken haze of a night?

It's folly to think that the same level and style of scrutiny need be applied to both. You aren't wrong to paint the alternate picture for your friend's case, but it's sidestepping the issue in question (e.g., potential harassment in the workplace) to attempt to make that equivalency here.

Yes, my point is that it's completely reasonable to second guess stories we hear. It's a normal, everyday behavior and one which gets us closer to the truth.

Due to her not being drunk I give her retelling more credibility, but that doesn't mean she should be unquestioningly believed.
