I just posted a sentence like this on FB. What word would you put in the gap? We or us? Both sound wrong to me for different reasons.

[It's] a thick brown vinegary sauce with the consistency of what you, though not _____, might call jelly. We would say jam.

You're in a jam about jelly? I'd say "we."

We.

"We" was my first thought as it fits grammatically but it just sounds wrong when I say it out loud. Maybe it's just me.

Interesting. I'd say "I". "We" sounds wrong to me too.

Well - I just came back to this and now I'd say "We."

Chiming in late, Kalleh, but I prefer your alternative "I" even tho it doesn't convey Bob's precise meaning. Just something off about either we or us in that sentence.

Yes, I agree. Now I do think "we" sounds better, with the connotation of "you" being plural.

I'd say or write "we" in the gap. (If one wanted to be pretentious, I suppose one could use "one".
