I fear something bad might happen. She is living by herself. Her sisters try to help but she tells them to leave in a few days. She has tried several times to reheat food in Tupperware on an electric stove. I'm afraid for her life. Today I went to her home and it was full of smoke and she didn't even know it. I asked her where the smoke came from an she said she don't know what's going on. Please I need some help
