I Was A Badass....

Your sister? The same one involved in the property fiasco? RIP either way.
No, she was the older of the two. She was gone before my Mom was. Early 50's. They treated a tricky brain tumor and "you never know" what people tell you. She claimed it was going to be OK but in about a year? it "came back." Was in a deep part of the brain could not be treated further
