3 nights ago my wife was out late for a business dinner. I expected her home around 10pm. At about 11:30 that night, a man I have never met calls to tell me my wife had too much to drink, and so he is putting her in a hotel room for the night. He said she was too drunk to call herself, but not to worry he was taking care of everything. She returned home the next morning with no memory of the night before, and a large bruise on her arm. She claims nothing happened but I am worried.
