Once you are out of your house, call the fire department from a neighbor's house.

Get out of the house or I'll call the police.

Now whenever I hear of a friend who's lost a loved one, I no longer call with the polite offer, "If there's anything I can do…" Instead I try to think of one specific task that suits that man's need, like taking the dog to the boarding kennel, or house sitting during the funeral.
