These have saved me from losing sleep on my travels so many times. First, finding myself in a hotel nextdoor to a synagogue that hosted loud children in their yard at 7am singing dreidel songs at full volume. And now, this moment, finding myself at a boarding school where my dorm mate is a 55-year old woman from Norway, our beds two feet apart. I adore her, we squeeze hands goodnight before bed, but she listens to loud podcasts while she sleeps and snores abundantly. I almost stopped loving her. But then, I just click on the noise-cancel feature and everything disappears.
