Just another day

An explosion shook the room, scaring aliens. Humans just clasped their drinks tighter to prevent spilling.

"Why aren't you afraid?" A multi-legged creature asked. "Whole planets exploded during this war."

"We've got an arrangement," a human answered. "All parties leave us and survive."

"But you're defenseless! All humans do is... nothing."

"We used to be powerful, but did it help us?"

The man counted: "Daleks, Cybermen, Axos, Nestene. Others. If not for the Doctor, we'd be destroyed many times over. Better just dawdle."

Confused, the alien glanced outside: "Look, snow!"

"No, dust from a starship. Someone didn't honour the arrangement."
