I keep everything on my phone calendar too, but he is not able to maneuver around much on his phone anymore. Just can’t remember how. He can answer it…when he will, he usually ignores it because he doesn’t want try to have a conversation on it. He can call me or his brothers and can open some apps he enjoys like You Tube. I am continuously showing him how to search for topics that might interest him. It’s just so hard for him to be living in a tech world and not able to maneuver about in it. .
