They call a lot around noon and dinnertime, and the number changes a little each time -- but always no name in call display. I never pick up the phone, just google the number to make sure it's no one I know (friends + relatives + neighbours email or text me or knock on the door). I feel sorry for all the seniors who are not online etc. I'm 75; a senior cousin of mine just listens to the answering machine then if it's someone she knows, she picks up the phone.
