how do you even start an rp do you just shot an ask with a weird sentence like ‘do you have painkillers’ or ‘what are you doing herein the morning dressed like a 30s supposed-gentleman’

(Well, from what I’ve seen, there quite a few ways to make a starter. Ones like you mentioned are good. Doesn’t just have to be a sentence, though, if you’d rather something that creates more of a setting. They can be sent through asks or through a post with the other mentioned/tagged, but the latter might be harder to notice… Other options for starting are responding to memes that can lead to a story or open starters the one you want to rp with has made. Really, there are any number of ways.)
