Yes there will be some secrets...for example if let's say my parents have a negative comment about my husband which I feel is just a misunderstanding or an incorrect perception, I dont feel it is necessary to share it with my husband and plant a seed of negative feelings in his heart. I'm sure he would do the same. If it is some mistake one of us made that can be corrected, then we would share with each other.
However, as far as I am concerned, I am an open book in front of my husband. He is fully aware of all my activities and has the right to know. We don't poke at each other though and try to give each other room.
Completely the same! If its something that will unnecessarily hurt the person leading to more misunderstanding...theres no need to discuss. Somethings are better left unsaid...for the most I'm also pretty open about everything.
