I’m currently discussing with someone else (in email) a particular book; doesn’t matter what book. Point is, they said, “Well, how come she never says anything about such-and-such? Wouldn’t that be an issue?” I want to say, “For the same reason Jack Bauer never goes to the bathroom,” but first I need to make sure that’s true.
Absence of evidence is not evidence of absence. Some things aren’t worth mentioning; doesn’t mean they don’t happen to the characters just because we don’t see them happen. However, if Bauer was ever in a dimly lit restroom and encountered a thug hiding in a stall, there goes my example. (Or I could amend it to “unless it’s important to the plot”.)
