Happens in Threes

We have suffered a loss in our circle of friends this morning. While I didn't know this person, his wife at one time was a good friend. The circumstance behind his death is a little iffy but it's just another visitation we will have to go to. My hubby says things happen in threes, so what exactly will be third is a little scary to me. We just had a thing of threes happen the first part of december and now this. It seems a little to weird for me.
