adversity makes strange bedfellows

The phrase "adversity makes strange bedfellows" means that in difficult or challenging circumstances, people who wouldn't normally associate or work together may form alliances or come together for a common cause. These alliances may seem unusual or unexpected due to the contrasting backgrounds, beliefs, or interests of the individuals involved. The phrase emphasizes that when faced with adversity, people are willing to put aside their differences or prejudices and collaborate with unlikely partners.
