A pretty off beat topic....
But this is how i have seen understood and interpreted numbers...
Number 1 is a simpleton,basically a loner and is every ready to help people(read as numbers)around,he is easily manipulated and is under number 2,his closest friend.
Then comes Number 2.....a smart female,a wisp of a lady still can think on her feet,knows how to treat whom,respects her elder brother number 4. Then comes the big fat lady....number 3,the "odd" one out in the series of youngsters,she like a mother ,a strict mother to 4,does not like 5 but is greatly influenced by 9 and often rebukes 2 for her immature ways. Number 4 is a handsome working man,who has intentions of being romantically involved with 5,but constrains himself.A caring brother to 2 and a wise guide to 1 also a very obedient son to 3,and pays high reverence to number 8.
5 is wealthy lady to whom lady luck has always been very fortunate.Has nothing much to do with other people (again read a numbers!).Likes 4,but wants him to make the first move.Her closest friend is 6.And also she has a brother in 10,same family but never too close! 6 is number 5's wise,mature friend.She going steady with 7.Maintains work relations with 2,3 and 9.
7 is a scared and mother pecked son of Number 8.Loves 6,but does not want to admit.Basically a loner. 8 is a dominating mom,likes to keep hold of her family,which includes number 9,her husband.Keeps a strong hold on 7,does not actually adore 6 but knows that 6 keeps 7 happy.
A godfather sorts in the number family,Number 9 enjoys undisputed respect and reverence from all.Loves his family and has a close confidante in number 10 . Number 10 a rich brother from 5's family,keeps close to 9 and is with him in all good and bad deeds.
