Obviously ...
I mean im not even exactly sure how dialogues works so far, since i keep reading about people missing this one or that one ... but i still somehow manage to have them all, or more likely manage to not even realize that i missed some.

I certainly not quite like the idea of talking everytime we get to camp, but im not exactly agaist it ... as long as we are talking about those companions who are just camping there anyway. :-/
But it sounds like much less good idea for the others, since then our companions will demand imediate return to camp, just so we can talk. :-/
Try to imagine the situation:
- You just finished fight against some bunch of goblins, or gnolls, or w/e ...
- Gale wants to talk to you ...
- So you gather your things, and go to camp ...
- There Gale summons his mirror image and start to admire himself, not care about you at all ... O_o
Or another one:
- You just finished fight against some bunch of goblins, or gnolls, or w/e ...
- Gale wants to talk to you ...
- So you gather your things, and go to camp ...
- There Gale asks you how did you like his Stew (or w/e he was cooking) ... O_o
Or final one:
- You just finished fight against some bunch of goblins, or gnolls, or w/e ...
- Gale wants to talk to you ...
- So you gather your things, and go to camp ...
- There Gale just stares to fire and tells you to "Go to hell" ...

As it is right now it makes perfect sence to me ...
Day is intense, we focus on our curent problem all the time, and dont disctract oureselves with other matters.
Night (or evening if you wish) on the other hand, is easy time, we are resting, we have time to think and talk.
I agree it would be nice, if our companions say something like "i would like talk to you before we go sleep today" and maybe either some indicator that you have conversation pending before you go to sleep, or posibility to talk with our companions in the morning after sleep would be nice.
But i dont like the idea of interupting our traveling just bcs we just gathered enough aproval, so our companion have sudently something to say. :-/
