Pairs?

I am unsure if it is a good thing, or a bad thing. There is a chinese saying 好事成双。(Good things come in pairs). I wonder if it applies otherwise. Because lately, I've loss yet another grandmother. 

Looking back retrospectively, making the trip home in December was the best decision I've ever made. Little would I know that that trip would be the last I've seen my grandmother. 

It did not come as a surprise definitely. We all know that she has been very weak lately, and having trouble with daily chores herself. She had a very good life, lots of grandchildren and filial children who love her very much. 

I will miss you. Ah ma.
