Five minutes later:
"Da-ad..."
"What?"
"I'm thirsty. Can you bring me a drink of water?"
"No. You had your chance. Lights out."
Five minutes later:
"Da-aaaad..."
"I'm THIRSTY. Can I have a drink of water??"
"I told you NO! If you ask again, I'll have to spank you!!"
Five minutes later... "Daaaa-aaaad..."
"WHAT??!!"
"When you come in to spank me, can you bring me a drink of water?"
