I always try to read everything, if not immediately, between poses and such. Sometimes when teleporting and following, I might miss some context around that area.
When it comes to ooc, I consider that the ‘rules’. I’m not sure I’d tell on anyone (unless it was harming someone’s consent), but I make sure I follow what’s outlined there.
The in-character text I try to follow so that we’re all experiencing the same thing. I consider it cannon. If people changed a few things for a scene, I’d probably roll with it, but the next time I’m around, I’d assume the description is still the reality.
I only look at the picture for vibes - I don’t assume too much from it. Maybe I’m just used to all-text, so I consider the text pretty important.
Some of this is in the tabs, so perhaps I miss things, especially when others are describing stuff in their own poses about what things feel like or what they are around. I am usually focusing on my RP partners. I’m pretty likely to be pretty lenient on what others want. But all the text having to do with a scene is important, though, including what’s already there. I definitely prefer to be well informed about where I am and what the expectations there are - most importantly ooc - because that extends beyond our own RP scene.
Just some thoughts on my own experience!
