Easiest trend I can explain with my method is that the longer I have to sit down, think, and explain specifics on how my character acts...

The more I feel pinned-down and constrained by stuff that didn't really happen and may not have been thought out too well, so I get bogged-down re-checking how my detailed character "should" behave and trying to force myself to and the character to fit into an RP.

Meanwhile, quickly slapped together characters of little more than a name and a picture usually end up having a "lived-in" perspective and often end up in RPs that last considerably longer. As responses are candidly what are felt most appropriate for that moment in the RP and everything develops with the RP's trends rather than against it.

That's just how I'm wired, though. And I'm sure if I overthought a character just enough they'd fit a given RP perfectly.

Anyways... back to a moment of writer's block... sometimes it's possible that, like the writer, the character can have a hard time keeping up with the plot.

A way of keeping the events of the RP in the forefront of one's mind is to re-state what has been going on, a brief moment of reflecting on the situation can clarify many a plothole enough for a means to react to become apparent.
