"I have an idea for boosting my performance."
"You wisely coached us to use all of our vacation days every year."
"Because we come back recharged!"
"Our renewed motivation is more than enough to compensate for ths missed days."
"My plan is to leverage that competitive advantage."
"I'll take a fifteen year vacation and return ten minutes before retirement."
"Then I'll be so recharged that I'll pounce and do twenty years of work in minutes!!"
"Unless it's near a holiday, in which case, do you mind if I leave early?"
