My father is 96 and lives in Arizona. I live in Iowa and get down there as often as I can. I talked to him on the phone, but today I spoke to him and he swore it wasn't me and told my sister and Mom to hang up the phone because the call was a scam. I'm going down next week. Thanks to your website, I think I'll be okay with Dad, but Mom is very argumentative and insists on keeping him at home. Please give me some advice.
