There is a six year and nine month age difference between Boy-Child#1 and Girl-Child. They rarely bicker. They will never attend the same school. They will never share the same friends [except all those crushes she will have on all the hot guys he'll bring home one day]. He is kind, patient, helpful, giving, protective, ...fill in positive attribute here... with his little sister. In return, she worships the ground he walks on. Not only does she think that he's the greatest thing that ever lived; she also thinks he's very comfortable. Big brothers make the best pillows.
