How would you describe how the death of their four-year-old son set off a disastrous chain of events for the family

It would give the mother and father depression, causing them to be too sad for work. They'd cry on their papers and probably refuse to do them. Then they'd get fired, and would'nt get a payment. Without money, they can't pay taxes or bills, so they get kicked out of their apartment or home. Then they'd become homeless, and an aunt, uncle, or grandparent would have to take care of them and let them live with them, but handling people with depression would be too difficult, causing the relatives to overwork, not getting enough sleep.
