Staying at a youth hostel, I started to feel the bed sway in the middle of the night. It wasn't just a gentle sway; it was rhythmic. A female voice whispered softly, "Be gentle... don’t wake anyone up..." A male voice gasped, "Hold on, almost there... this thing is too tight..." I curled up tighter under the blanket, my heart pounding. Then I heard a "click" sound. The male voice sighed in relief, "Finally got it off! Your thermos lid is way too tight, I was dying of thirst."
