A case of do or die

In order to write a sensible shopping list and not buy stuff we already had, and forget things we needed, I was checking through the cupboards. Lasagne - needed. Dried apricots - needed. Cereal - okay for. Rice; basmati, plenty; long grain, should be okay ... ooh what's this? A don't remember buying a box of Uncle Ben's Florentine rice, I wonder how long it's been there. Ooh look, it's got a price ticket from the shop near the old house, and we've not been there for ages. Being TOGs and proud of it we take not a jot of notice of trivia such as sell-by dates and associated nannying, but a lot of squinting located the best before date, which caused a dilemma.

The BBD was The Boy's birthday. The original one. Do we have the rice to celebrate their joint 21st anniversary on May 20th or shall we keep the packet as an heirloom?
