There are some pretty cool things surrounding the number 9.
Nine is one of my favorite Fellini movies.
Nine inch Nails used to be a pretty cool band.
Nine is the month of your daddy's birthday.
9-09 is Auntie Ambee's Birthday.
If the denominator of a rational number is not divisible by 3, then the repeating part of it's decimal expansion is an integer divisible by 9.....DUH!
Nine is seen as the number of completeness. (whatever that means).
But my favorite thing about the number 9, is that today, you are 9 months old.
