Hello ! Thanks for taking time in reading this.

I was having a, I don't know how to call it. A discussion? A disagreement? Something when two people have different opinions on a subject, with a friend. 

So I come here to ask what's your opinion on the subject. Maybe I am wrong, maybe he is. 

The subject : 

I am a firm believer that what happens in IC but that doesn't concern your character, nor is a GM post or something that affects the story but it is simply a discussion between other characters of the RP and your character is not even near those said characters, is not necessarily needed to read for a successful interaction with other characters.
Let me explain this better by giving an example :
My character will be called A and the other will be called B,C and D.
A talks with B in a room and C and D talk in another room that is nowhere near the room when A and B talk. 

I was stressing the point that is not a [i] must [/i] for a RPer to read discussion between C and D because :

[list][*] it may influence decisions later when A interacts with C and D unwillingly (subconscious mind or whatever you wanna call it)
[*] The RPer may learn information that A cannot know/should not know yet. Maybe C and D plan a murder and A and B are cops.
[*] I think I could give a few more examples but I think you get the idea. [/list]

So. I would like your opinions on this subject. Is it 100% needed for a RPer to read posts that don't concern your character, nor is a GM post or something that affects the story ?

I for one say that it's not a must. I personally read all the IC posts after some time, that is, of course when I'm not GMing that RP.
