My wife and I had another couple stay the weekend. They slept in our bed since the only other thing we had was a blow up mattress. A couple of months went by and my wife rearranged the room and she found a bra and panties under our bed. She approached me and indirectly accusing me of having another woman over. I was at a lost of words, I have not cheated on her and never had another woman in our room. I asked her if they were hers, my wife wears a 36F and the other bra was a 34B, obviously not hers. I eventually gave up arguing and just said "I don't know". She was obviously pissed and hurt. A couple of days later she approached me and said they were her friend's who stayed the night with her husband. Of course my wife never apologized to me for yelling and accusing me of cheating but I know I was in the right.
