Dorothy: Rose, have you been drinking much of this?
Rose: Only at night when I can't sleep.
Dorothy: This is loaded with caffeine.
Rose: But we need caffeine, especially women our age. Or our bones will get brittle and we'll walk all stooped over.
Dorothy: That's calcium, Rose. Calcium, not caffeine. This is what has been keeping you awake.
Rose: You mean, if I stop drinking that, I can sleep?
Dorothy: You may even blink again.
