Among the many odd things that happen in places of lodging, this is a story from our first or second summer in business.
It seems that one of our female guests wandered out of her room late at night without a stitch of clothing and wandered into another guest room where the sleeping couple had apparently forgotten to lock the door. The couple in this room were there for his birthday, the stay was a gift to him from his wife. The man awoke first, saw the naked woman in the room and thought "This is the best birthday present EVER! My wife is soooo cool." Fortunately, (or unfortunately depending on your perspective) at this point the wife woke up but before she could react the sleepwalker turned and exited the room. I gather she headed downstairs.
My husband & I, despite the fact that we live in the house, were totally oblivious to this entire escapade until the next morning when the guests from the 2nd room told us about it after breakfast. They thought it was extremely funny. Adam & I were astonished that they had managed to have breakfast at the same time as the sleepwalker and her husband and remain totally cool about it, not saying a word while they were still in the house.
Both couples were there a 2nd night but I'm pretty sure the birthday boy's wife made sure their door was locked before going to bed!
