Tell her about the price of grain
It sounds like you are a farmer. So just tell her about the windfall you will have in the fall. With all the prices of soft commodities going up every farmer will benefit.Also if your a farmer maybe you can write it off,perhaps you needed it to keep coyotes off the property.
I would just keep buying more, they only get upset in the begining. Eventualy they just give up!!!!!!!!
