Entrepreneurial exes meet once a month, bringing their baggage -- emotional and literal -- to a converted cottage on a leafy Hanoi street to find a new home for items they can no longer bear to look at.

"(After a breakup) I'm very sad, I can't drink or eat... but after a while I pick myself up. The past is in the past," said Phuc Thuy, 29, who was selling clothes, purses and even a tube of toothpaste she acquired during a former romance.
