I have a stash.
I hide it in the freezer and only ever bring it out after the girls' bedtime so they don't see it and make me share.
As soon as the coast was clear last night I put on a CD (Jethro Tull, Best Of) and raided my stash for the biggest piece of chocolate I could find. I was reclining on the couch, enjoying my antioxidant packed goodness, when I choked on my own saliva.
After a good few minutes of loud, breathless coughing, sweet and intuitive Miss F appeared by my side. She knelt down and put her head on my knees, looking up at me.
When my strangled coughs subsided long enough for her to get a word in, she sat up and said, "Mum.. I can't sleep with all this noise, you know."
