W comes to me after SIL leaves a few minutes ago, and asks why I mentioned "friend" to SIL. I said it just came up, and was wondering what happened since they don't talk anymore. W then said that she thought I was trying to pry information from her, which actually isn't true, it just came up. I told it didn't matter anyway. She said she found it odd that I asked about friend, I told her I found it odd that she cared. She rolled her eyes at that and said something about invalid argument. I then asked if she needed more clarification, and she just walked away.
So she had the chance to say something, but declined to do so. Disdain or hiding? Can't tell, but once again doesn't really matter I suppose.
