Say Yes

"Daddy, can I wear my sleepsuit?"
"No, you're too big for it and it's 3 o'clock in the afternoon."
"Daddy, can I use your saw?"
"No, you're only four and you might cut yourself!"
"Daddy, can I cut up this polystyrene to make some snow?"
"No, it will end up everywhere."

Sometimes in life I think it's better to just say Yes.
