Whenever me or my friend get a writers block.
We talk about a whole lot of silly head-cannons about our characters, or ideas for the future of the Rp.
Or ships we know wouldn't work between characters.
And then we are all inspired again.
Yeah, usually I'll either watch/rewatch some anime, read one of my many books, or do some off the side writing in one of my notebooks. I don't have any irl friends who RP. :/ At least, not that I know of.
