I know that my in-laws only have two sons and it puts them in a very difficult position when the two brothers get testy with each other. But just once, when my H is clearly and unquestionably in the right, I with they would just back him up. Just once.

It's good to be on your husband's side.
My FFFC is I ate POORLY today. I had bagel chips, m&ms AND Reese's cups. I don't usually do that.
You are not alone. I had not one, but two cookies after lunch (big Potbelly cookies), and ice cream after dinner.
