This is all just coincidence right?

So my best friend and I live oddly parallel lives. My oldest daughter and her daughter are one month apart. My son and her son are one month apart. Her son was hospitalized for pneumonia and one week later my son was hospitalized with a rare allergic reaction. We close on our house and move in with my parents. One week later they close their house and move in with his parents. When my friend's mother died I told my husband that I was worried about my Mom. I wanted to keep a close eye on her for the next week. I was joking, sort of. When a week went by I was a little relieved, ok a lot relieved. Did I ever tell you I can be superstitious and irrational, full of all kinds of magical thinking. Then on day nine my Mom tells me that they've found lesions on her liver and she needs to go the James for a CAT scan to see if her breast cancer (which is all gone) has metasticised to her liver. I'm worried. Her heart can't stand another round of full blown chemo. The Greatest says I'm borrowing trouble, that there are all kinds of things that could cause the lesions. But what can I say, I'm a worrier. My Mother will be alright, because she is my Mother and she has to be.
