If you ever feel embarrassed about RP or writing fanfic, know that Laurie R. King, a New York Times bestseller regularly RPs on Twitter as her main character Mary Russell… whom is Sherlock Holmes’ wife. Like it’s a best selling fanfic and her twitter is great.
She updates about her life with Holmes,
Gets annoyed when those who review her books categorize her stories as fiction,
And gets flustered when people misquote her stories to King! Like her muse gets mad at her.
That’s hardcore RP done right there. So a well known author is also an RPer of her OC and I think that’s awesome.
