Appreciation...Not

My MIL is in her 80's. Recently she began using a cane full-time. She has artificial knees. She will not take showers, she will only take baths...upstairs in their house, as it is the only tub in the house (the main floor bath is shower only). For years now, my FIL has had several contractors in the house in order to make life for MIL a little more convenient. One day she caught one of the contractors in the house with FIL and she threw a fit right there and nearly gave herself a heart-attack kicking the poor man out of the house.

Last night, MIL and FIL got into a shouting match in a public restaurant. He mentioned that this winter he will have someone come in a put in another bathroom, just for her and she went ape-shit.

The most frustrating? They have the means to get it done, but she is so ungrateful and always thinking there's an ulterior motive that she refuses to let anyone do anything nice for her. It's really sad that someone could put their stubbornness and pride before their own safety and well-being.
