lady i take care of just dont seem to have any common sense with most things. do these patients lose common sense? its so frustrating for me, cuz she knows she's right about a certain situation and u cant convince her otherwise, even though if she used common sense she would get it. example, i noticed she was starting to spit everywhere, after a day or so , i asked her why she was doing that. she said the spit in her mouth was ganna kill her. i told her to think about that, if swollowing ur spit is ganna kill u, we'd all be dead. but she is dead set on it.
