Ok, as I play a mute Bolia, I have to deal with nothing but emotes when in her shoes. I have never once said what was in her head, yet people always seem to know exactly what she is thinking. Understanding her signs is another thing entirely.

I use "as if" and "seems" quite often, as that leaves the mood open for interpretation. "Is" is also not the best of responses for mood, as people will not know exactly how your character is feeling.
Aeshion is happy.
Aeshion looks happy.
There is a huge difference to those two statements. One is peeking directly into her mind, while the other is surface only. Let me expand on why.
Aeshion is happy. End of story. people know that you are happy, but have not really been drawn in.
Aeshion looks happy (but is really rather down because she has yet to find any flowers in the hills, but she does not wish to upset the mood, so puts on her smile)
Everything in () is what you know, but can't be seen at first glance. Now, if you want others to ask you about it...
Aeshion looks happy, but you may notice that her smile slips every time her eyes drift to the door, perhaps gazing out at the distant hills.
That tells players that you are interested in talking about what is bothering you character, but does not give awy too much. In real life, you can indeed tell when someone is looking off into the distance, and see small changes in her face. Now, some folks in the room may not have seen this. "you may notice" lets players decide for themselves what their character may see. "Perhaps" gives them some thought on what you are thinking, but not what it is. The entire statement is only what can bee seen by other's eyes, yet gives the same mood as the other example. It also engagues other players more, and draw them into you roleplay, as they, as the player, start to wonder what might be up. Telling them right out detracks from that, and takes out any mystery in the situation. Let's take the first again, and see about a response.

That is actually hard to respond to, as you already know what is bothering her. You can ask "Aeshion, what is bothering you?" to which she would respond in handspeak (if you know it) "I hoped you would not notice. I have yet to find any flowers in the hills, and it is making me sad." That is very redundant and hard to make into a conversation. The bad breath smell is the same. No one is going to ask what you smell if you already told them 'mentally'.
So, in this way 'self' messages do detract from RP, as it predetermines the conversation to an extent, and robs the other players of that 'wondering' moment. It is that wondering that I use constantly to draw people into my roleplaying and make them interested. Call it a small form of manipulation, but it works very well. Ask anybody who has met Aeshion.
