Our granny’s are the best in saving their hard earned pennies even before these modern banks came into existence. Yes, I mean it!! Just check out your extended memories! Our grandma’s always had her savings in spite of all the expenses she bared. She cautiously managed all the expenses within the income and even saved a good sum of money in her locker which will come out only when there is a sudden need. Can you guess what might have been her safety locker?!Any guess?!
