<human>: My wife and I just had our first child and her parents came out to see the baby and help us adjust to our new life. Her mother(Jane) came out first right before the baby was born and everything was going fine. Her father(Joe) came out a week later after the baby was born and that is when things started to become more stressful in the house.

It is very easy for me to see that Jane is growing tired of the constant sarcastic remarks that are being thrown her way. I work from home and on multiple occasions she has come into my office crying just looking for a hug, which I gladly give to her. She waits in the office until she stops crying and then goes back out like nothing is wrong so she does not startle my wife who is incredibly hormonal right now.

I am fighting the urge of just pulling Joe aside and asking him "what gives?". He is a smart and nice guy, so I know he can see that he is slowly whittling down his wife's confidence and emotional stability, yet he continues to do so with blatant disregard to her feelings. I don't know if Jane has brought this to his attention but it would be very hard to miss.

Do I say anything?

Can you provide a brief overview of the text?
<bot>: Do I say anything to my father in law about his struggling marriage that I believe to be the result of his actions?
