“That's what siblings are: a reality check. Try to become someone you're not - affect an accent, or start quoting the temperature in Celsius instead of Fahrenheit- and they're the ones who smack you upside the head. Siblings are like potters; they try you by fire, glaze you with taunts, finish you with well-aimed jibes. If you emerge from that kiln without cracking, you can survive the world.”
