Six Manhattan trading desks liquidated their emergency canned-bean reserves on Friday afternoon. The panic started minutes after MarketWatch published an essay by a 64-year-old lifelong renter who reported feeling hopeful about the future.

Quantitative bears immediately flagged the woman's cheerful resilience as the final, fatal stage of irrational exuberance. When a permanent tenant near retirement age refuses to weep into her lease agreement, the smart money knows a 1929-style liquidity cascade is only hours away (the Dutch tulip bubble burst under identical psychological conditions).

"Unhedged optimism in the senior rental sector means the commercial real estate market has detached from gravity," said Vance Sterling, chief catastrophe strategist at Abaddon Capital. "We are shorting everything except shotgun shells and landlords."

By the closing bell, the Federal Reserve had convened an emergency committee to hike interest rates by six hundred basis points until American tenants stop smiling.
