I was in a hotel bar and noticed two couples across the room were hitting it off. One couple was younger, late 20s or 30s. Attractive brunette woman and athletic looking husband or boyfriend. The other couple was older. Auburn haired woman in her 50s, average looking husband about the same age. They all got up and left together and I made not of what floor the elevator went to. Went up myself a while later and could hear them through a room door. I think they switched partners.
