This is why I have to stretch and remember to add more details of that nature when I RP otherwise I will completely forget about it entirely. I know other people care about it more. My mind's eye is beyond fuzzy so I don't actually rely on it much or use it in RP much. I suppose that is why I enjoy the abstract more.
I get into it when two personalities clash and then I can sit and try to anticipate how the other character will react to a personal insult, how they will react if someone they know is insulted, what they will do if presented with a scenario they fear, what they will do when a matter of passion is involve, etc. Or piecing together behavioral patterns. When Zandral's (then) boyfriend spoke of some other woman, the first thing I did was review the list of females he had spoken of to Zandral recently, figure out which one Zandral would focus in on, and then toss out a line to see if he bit and if Zandral's assumptions were correct. She was only partial correct though.
Or later when figuring out how Zandral would Tell Illysia about her boyfriend, I imagined what Illy's take on Zandral having a boyfriend would be, what the general stance of their family would be on it, the state of Illy and Zandral's basic line of communication, and how Zandral would twist and turn to couch the infomation so that it would raise as few red flags as possible with Illysia. And I did all of this even though I controlled both characters, which in their case was rather fun especially when they argued completely opposing points. the two of them arguing from polar angles let me turn situations around in my head and explore both sides simultaneous in real time.
Now that I think about. To be fair, I actually get bored if I spend too much time reading about scenery and not enough about the character's internal motivations and battles.
