My OH who has FTD is currently sitting on the step up to the French windows - i.e., in the garden, but with a door open behind him into the house. he probably fell, but he won’t admit to it. I didn’t miss him until I went to find him to tell him the evening meal was ready, so I’ve no idea how long he’s been there. Probably no longer than half an hour. I asked him whether he needed help to get up (actually, I know from experienceI can’t be a lot of use, but we have various strategies we can employ if he’s downed: worst case scenario, I call his sister and brother-in-law to help, but they are busy people and half an hour’s drive away) and he told me in no uncertain terms to go away, so I did. He knows dinner is ready, I think he’s trying unsuccessfully to get up. What should I do? The weather’s mild, it’s still light. My instinct tells me to leave him until I’m actually worried about his physical welfare, and then call for help
