I can hear DH while we are working. I don't listen but he's background noise and my brain notices and logs it. This morning my brain must have gotten enough data points because DH was on a call and my brain asked: have you noticed how he more easily complains about a woman's behavior than a man's, like in this current call?

I said no I hadn't and I asked my brain to defend its statement and it came up with a number of examples, and helpfully compared it to personal situations and his attitude. 

While I agree with my brain and we will file that away as a "thing to consider" when dealing with DH, we both agreed that any extra thinking should be focused on something more fun like plots for a new Deadpool movie.
