A woman is sitting in her hotel room when there is a knock at the door. She opened the door to see a man whom she had never seen before. He said "oh I'm sorry, I have made a mistake, I thought this was my room." He then went down the corridor and in the elevator. The woman went back into her room and phoned security. What made the woman so suspicious of the man?
Why would he KNOCK on his OWN hotel room? If it was his, he would have simply just used the keys to open the door.
He might of knocked becasue he was expecting his wife to answer the door. He might not have taken the key with him.
I think the woman was just the suspicious type but the man should have shown some confusion. Instead he just condidently strided away, like he always knew exactly where he should (or should not) be. :)
