roleplaying and stupidity

warning! eng is not my native language so i may not be able to explain what i really care about. don't bother with mistakes pls i’ve learned how to avoid censorship, to get deepseek to produce more or less atmospheric texts and to stick to the canon (he doesn’t make characters too kind, etc) BUT it constantly spouts some kind of nonsense. i don’t even know how to explain it — he just writes some incoherent nonsense; especially common are idiotic analogies like «like a person who… “didn’t turn off the iron”» even though there’s no mention of the iron. or i don’t know what to call it, here’s just an example: «are you always like this, or is it just on mondays?» «let’s go before i change my mind and decide that cocktails at a bar are better than cocktails with a guy who didn’t even tell me where we’re going.» WHAT’S THE CONNECTION AT ALL OR WHY CAN’T IT EXIST AT THE SAME TIME? he also constantly uses the conjunction «and» i.e. he doesn’t connect phrases properly but just speaks in «and»! also he doesn’t follow the OOC notes at the beginning of the post like «don’t roleplay this character, he’s mine». how can i get him to write properly? is there a prompt (MY ONES ARE ALREADY HUGE!)? and how do i describe this behavior and explain to him that he can’t do that?!?!?
