hahaha.
those secret funds are called hesokuri in japanese.
i too have a virtual maintenance fund where it accumulates each month automatically in my bank account.
basically the lump some for me just falls into individual mini-accounts inside my allowance so i dont have to worry about anything. like money for dining and misc, gas money, car parts/maintenance fund, new car fund, music gear fund accumulates separately. this is why i dont discuss about buying a new car or car parts with my wife cause it all comes from within my allowance. she doesn't care.
