DEAR HARRIETTE: I went to visit my friend in Las Vegas a few months ago. She moved there earlier this year, so I was excited to see her new apartment and meet her new friends. I slept on the couch while I was there. One night she went to sleep early, and her friends – including a man she's been seeing – stayed in the living room with me. The second they left, she walked out of her room and accused me of flirting with her love interest. I was completely shocked. I have no idea why she would come to that conclusion. She wasn't in the room, and I wasn't the only woman present, so it felt random that she would point the finger at me. She apologized a week later. Do you think that my friend could have some sort of hidden animosity toward me? She never really gave me a reason for why she pointed the finger at me that night. – Strange Accusation
