Re: Is husband's statements to sister unnatural??
I would have to agree with Mgirl.
I have 4 sisters, 3 of which would fall over dead at such a comment from me. The fourth one just simply has this same personality.
It's who she is, so I have no problem goofing around with her on this level.
It's no big deal. Even my wife understands that this is just who she is. My wife will joke around with her in the same fasion, even though that is not my wifes normal personality.
In my humble opinion, If it's not hurting anyone, I think you should just leave it alone.
