" Mr. Albert? Mr. Albert?” Harley said.
“Just Albert’s fine,” Albert said tersely.
“Me and Janice are thirsty.”
“I’m sorry, but I don’t have any water on me.” He managed a tight smile and moved on. But now Janice was crying and Harley was pleading.
“We used to live with Mary and she gave us water. But now we have to live with Summer and BeeBee and they said we have to have money.”
“Then I guess you’d better earn some money,” Albert said. He tried to soften it, tried not to sound harsh, but he had a lot on his mind and it came out sounding mean. Now Harley started to cry, too.
“If you’re thirsty, stop crying,” Albert snapped. “What do you think tears are made of? "
