I have successfully used:
- time to take your pills
- it's such a nice day, why not go sit outside for a while
- go see what your friend across the street is doing ( they love that one!)
- getting up and walking out of the room he is in (when the above don't work and I can't take any more)
What other topics, activities etc do you use to distract raging, complaining, accusatory behavior in the elder you are caring for.
