"Asuma..." Kurenai held out a gift. "I got you something."
Asuma took it. "Urk...snork." He was already wasted from all the sake and cigarettes. "Wazzinet?" He opened the gift. "Crizzle mef?"
"You gave Asuma... crystal meth?" Kakashi peered at Kurenai strangely.
"Well, Kakashi," Kurenai smiled. "I know the best gifts are ones that are handmade."
