Late this afternoon my wife sat down on our bed (on my side) and noticed that the comforter was damp. She pulled it back and discovered that the sheets were wet through to the mattress and there was a blue spot in the middle of the dampness. I have no recollection of a wet bed when I got up in the morning. In fact, I clearly remember not wanting to get up because the bed felt so cozy but there is no way I could have missed that wetness. At first, we blamed a visiting dog but the bed was still made and I do not think the dog would have bothered to make the bed. For the record, I feel great and do not (as far as I know) have any problem with my bladder . I am baffled. Any thoughts?
