In laws

Is anyone else currently fed up with their in laws? I have just about reached the end of my rope. Today was just about the last straw. Not to get into any details, but my father in law, despite having been a member of the church for his entire life, has absolutely no idea how the gospel really works. He is the kind of person who reads the scriptures, not for personal insight or for greater understanding, but to get more ammunition for his personal beliefs. I am really tired of beating my head against that particular wall and am simply grateful that my husband understands so much better then his father, and doesn't allow himself to be sucked in to his father's delusions.
Anyone who is too confused, I have no problems explaining further, but not here! Thanks for letting me rant!
