I just got home and found a note that my mom and her 24hr sitter had gone to the store. When they got back my mom said she didn't go in the store and apparently stayed in the car while the sitter went in. I bought groceries the day before so am pretty sure there was no urgent need for any essentials and noticed the sitter had no bags when they came into the house. I am upset that my mother was left alone in a parked car even if it was just for a few minutes. She cannot get around without the aid of a walker and has mild dementia, CHF, and is hard of hearing. It was cold and raining this morning as well. Am I overreacting? Or should this be a concern that needs to be discussed with the sitter? I am too annoyed to talk to her at the moment so am taking this time to get some feedback and advice......any thoughts or comments will be appreciated. Thanks!
