I think they move too smoothly. I think it’s maybe a combination of the “ew, tiny things are parasites” and the “ew, smooth-moving things are snakes” responses, even though neither of those is appropriate for the silverfish itself. I think that’s part of what happens with the house millipedes, too.

I dunno, silverfish are smaller than flies, but they still give me that revulsion response.

Hubris is a kind of boastful pride–like a sense of invulnerability. It also implies a kind of dramatic irony, that this sense of invulnerability will eventually prove false. (The term comes from ancient Greek theater, where it’s often the Heroic Flaw that will eventually be the undoing of the tragic hero.)

Chutzpah is more…audacity, nerve, gall. A person with chutzpah doesn’t believe they can’t be harmed; they’re just willing to bald-face it out in the hopes you won’t actually call them on it. In English it can have a positive connotation, the way “cojones” tends to, but it can also have a negative connotation, like “cheek” or “gall.” It comes from Yiddish, where apparently it’s more uniformly negative. (Leave it to us Americans to interpret a condemnation of shameless effrontery as somehow laudatory.)

I guess I would say the key difference is that someone with hubris thinks they are invulnerable, whereas a person with chutzpah is aware they are vulnerable and absolutely refusing to act like it.

They’re definitely kind of related, but they just have really different feels to them
