And not feel guilty because I am the only one he has to talk to? My Dad calls me up to 8 times a day. My Dad is almost 90 and he is living in an apartment complex thank provides his meals, cleaning and are there in the event of an emergency. I work and he calls me all the time to either read me his mail, read me a catalog he received or what he is watching on TV. I have a brother and two sisters, but they live in another state. I work and I guess he calls me all of the time because he is lonely but when he calls me it's always when I am the busiest. His timing is perfect. I try and play golf once a week and even if I tell him I am playing he stills calls me. So bad, that I leave my telephone in the car. I cannot be the only one out there with this so-called problem. Any suggestions?
If it's not memory, then it may be that he is not able to resist the impulse to call you. Seniors often need that feedback and support. If that is the case, I'd make sure he knows how to call 911 for emergencies or get an emergency button and then let his call go to voice mail when you're the busiest. Explain in advance that you won't be able to take his calls, but you'll call him later.
Maybe, he's lonely and wants to chat. Can you arrange for a visitor to go to him or for him to attend some kind of senior events? Or, have you tried going to visit him for a couple of hours a week on your schedule and see if that helps?
