Disbelief

The woman that I am substituting for passed away this morning. I am in complete disbelief. She had a hysterectomy 3 weeks ago and we were told that they removed all the cancer on her cervix. My first year working here, she was the only special education teacher that was not new. So she had to teach all of us new teachers the ropes. She was only two years away from retirement. I just can't believe it.
