Okay, only really good RPers seem to get this.
When you play a certain character- no matter who they are, they need LIFE.
Yes, I understand. Your interpretation of the character may end up boring you or other people.
Aren't you, out of character, a pretty awesome person? You're pretty entertaining in person, huh?
Why don't you pour some of that into your character?
If you're too rigid with your character or so OBSESSED with staying in character, you will most likely end up reacting to something differently than the way the character might ACTUALLY react to it. In other words; think too much and POOF.
"I CAN'T HEAR MY CHARRIE'S VOICE ANYMORE DX"
You MUST enjoy your role to be a good RPer. Haven't you ever heard that "If you hate your job, you probably aren't any good at it"?
Let some of you flow into your character. It gives them LIFE! It makes it entertaining both to you, your role (DON'T MAKE ME GO OVER IT AGAIN) and those RPing with you!
If you're playing an "emo" or "dark"/mean/moody character, you can have a LOT of fun with that. 8D If you're a meanie, when faced with certain situations that you think your character may not do (but may/could do something)...at the same time...think. WhAT WOULD YOU DO IF YOU WERE HIM/HER?
Recently, my Sasuke RPer did something that cracked most of the people on my board up. Suigetsu was wearing a GIANT black coat. It's wintertime. He's like...COMPLETELY MADE OF WATER. So the RPer for Sui-kun gave him a "The Christmas Story" jacket, complete with arms that don't go down even when you push. I wouldn't put that past Suigetsu in character. <3
So Sasuke took advantage and subtly pushed/shoved/elbowed/bumped into him so that Suigetsu falls and starts...rolling...then he acted like nothing happened.
SASUKE COULD DO THAT.
FRANKLY, SUIGETSU PISSES HIM OFF SOMETIMES! XD He could have chosen to say something insulting instead, but pushing him still counted as IN CHARACTER and it was FREAKING HILARIOUS XD
What you do depends on YOU! If you can still hear that voice, you're probably still in character. Of course, if you don't know HOW to do this, wait until you're more comfortable with your character and wait for the situation to come up. The answer will come to you.
