Stephen, oh Stephen!

22 is my lucky number - brother born on the 22nd, sister born on the 22nd, son born on the 22nd, daughter born on the 22nd, grandfather died on the 22nd (OK, not so lucky for him), other daughter missed out by one day (spoil sport - not a team player) and the daughter who likes to be different - you guessed it, born on the 11th (that's half of 22 by the way)
