Input: This happened a few years ago.

After my father died of cancer (diagnosed and death all within 5 months), my mother went straight downhill. They were married for almost 50 years so they were always devoted to each other.

My mother started forgetting easy things within a few months of his death. Could no longer write cheques to pay bills. Could no longer drive. She fell into a deep depression where she would literally sit in the same easy chair all day and evenings. I know because I was taking my kids over to visit her almost every day during that first year. It got to the point where she smelled like ass and I mean BADLY!

My sister (I have 2) lived in the other part of the country so she had no idea what was happening other than the fact my other sister and I kept her up to date on our mother's degrading mental situation. But for some reason, I consider it human nature, she never really absorbed what we were telling her. She seemed to think we were making a bit of it up, that our mother wasn't as bad as we were making it sound.

So one day she finally comes to visit my mother. She was in a non-care home because she couldn't live alone anymore. I mean non-care in the sense that my mother still had to do some every day things but didn't have to cook or wash clothes. That was all taken care of for her.

I also have to say during this time my mother was diagnosed with Alzheimer's disease.

Anyways, my sister comes to town and I take her to visit our mother. My mother doesn't recognize my sister since she hasn't been around to visit. She came to our father's funeral but it was quite a few years that she's been around. 

So my mother says she has to go to the washroom. My sister seems to think "if she can go to the bathroom then her mind isn't as bad as my family has been telling me". And she says it out loud to me.

Long story short, my mother didn't raise the lid and sat down directly onto the lid. She proceeded to take a massive shit while sitting down. 

My sister finally goes into the bathroom to see what's taking so long and comes to tell me what  our mother did.

I kind of laughed and told her she had to clean up our mother and the toilet seat since she thought my sister and I were exaggerating to her for the past while.

I have to say my sister took it well and did what she was asked. She also told me she should have believed us when we told her how bad our mother went downhill.

I ask AITA because I could have easily helped her clean up our mother but didn't out of anger and spite.
