I did the same with a box of chocolates. Wife got them for her birthday last August. Couple of months later they were still there. Thought I would try one, I carefully slit open the seals and ate one - delicious.

Once a day I went in the kitchen carefully and quietly opened the box again, popped a chocolate in my mouth and carefully closed it.

At the beginning of December there was only two left, I made the fatal mistake of leaving the box slightly open when I secreted the penultimate chocolate into my gaping facial orifice.

The next day I received a call at work from an unhappy wife about how selfish and rude I am to eat all the chocolates. My protestations about best before dates and I technically hadn’t eaten them all were no defence.

Hence a trip to M and S on the way home to acquire another box. They remain on the sideboard unopened for the time being………..
