(Note: I just had LASIK surgery, so my eyes are blurry. I may not catch the mistakes when I write this...or care to fix them if I do).

The only time I think it is a problem when characters react opposite of what we hope is when they never react different than that. Like, sometimes, I play a character who is an angel. I play on the "Angels know Love and Protection." So, they don't understand fear, hatred, etc. When this is known ahead of time, you can EXPECT that this character won't have many emotions to show no matter the situation.

But then there's time when you get a NORMAL character being played, and they play them absolutely emotionless and there is no 'reasoning' behind it... That's the only time I might come out and say; "Hey, it's hard to really respond to the RP if you never show anything emotion wise... If you plan to keep acting like this, my character won't stick around..." And, in 1 x 1s, if someone leaves, the RP ends.

What I hate is when...I look for a partner for a plot and describe how a specific character they play will be demeanor wise...and they want to do it...but then completely flop the character into someone else...which totally throws the RP off... I don't mind if they ask to change it, but since the plot I was expecting called for specific types of characters, when they take a cold hearted guy and make him a softy from the get-go, it's just weird...and basically stops the RP. Growing to be softer hearted is fine, but not without depth to build to it.
