Grandma has Dementia. Phone call 1. Wanted her son to come set the clocks in the house weird we didn't have a power dip. Phone call 2. Wants to know why her son is working so late and she is hot and clocks are wrong. At this point I grab the spare key walk (we live that close) to her house knock let myself in temp is set to 79 degrees knock that down 2 degrees and check the clocks which are working and on the right time.
