Be Prepared!

A science fiction writer he knew always carried a black backpack that he called his "alien abduction pack." "Everything I need to survive for twenty-four hours in eighty percent of terrestrial environments." It was really a "I crashed in somebody else's hotel room at a con" or "the airline lost my bags" pack. Weaver had started carrying one as well and he was glad for it now. He could shave with his own razor and brush his teeth with his own toothbrush. He'd used up the bottle of water the day before but that was easily remedied.

As soon as he was done with his shower, hair brushed, wearing new underwear thanks to the "alien abduction pack" again, he was ready to face the day.
