My FIL's smart way of dividing his late wife's jewellery ! Brilliant decision..

]Dear Friends
I would like to share this with all of you...

My Mil's first death anniversary is in the next month . Four months after her death my FIL wanted to divide the jewelery equally among us, so he very particularly called both my SIL's along with their daughters (both have a daughter and son each) and every gram was divided equally in presence of an Achary ( gold smith). He weighed each one of them noted it down and was made into three parts.
My FIL told that he would like to share the gold equally to his three grand daughters, he put everything in front of them and asked them to choose, he politely asked us not to involve to avoid any controversies . The girls did a cool job they selected whatever they liked , my SIL's daughters are big girls (one is already married ) but still they were kind enough to make my DD choose first as she was the youngest.
Believe my DD almost got 400 gms of gold nearly 50 sovereigns, some new and some beautiful antic one's and half of it I have not seen it at all, MIL even possessed "Vanki"'s Vadyanam (waist band) which she has not at all shown it to me..I believe they are all ancestral one's which she acquired from her MIL..
But still I wonder what was in my MIL's mind.. why did she not want me to know about the jewellery she had, my DH was her only son and she loved and adored him but still she hid them from his only daughter ( her very own grand daughter) her character was really puzzling.

Even my SIL's were fine with my FIL's decision, and the girls did a tremendous job, they din't show any greediness, jealousy or anxiety when they were told to choose...
My FIL knew it before hand that the case won;t be the same if he would have asked us to share ( two SIL's & me) I am sure there would have been argument and disagreement between the two sisters itself.

If at all my MIL's soul come to know of this she definetly would be very angry with my FIL's decision because she told me directly / indirectly at least 100 times that all her jewellry will go to her daughters and not single gram I will get.
