In any case, it seems likely to me that the average player rests more than the average forum member.
Again, in my case, I don't try to actively avoid resting (it also seems odd to me). I do it when it makes sense (low on spell slots/companions complaining).
But I'm still confronted to this issue.
Finally, as has been pointed out, companions will queue up stuff to say even if they’re not sporting an exclamation point.
Doesn't work with the example I have given above.
And I don't like missing stuff that, to me, at least, shouldn't be missable.
