The real story of a box of chocolates

Eating a last piece of chocolate makes me have a little tinge of guilt, especially eating out of a big box of chocolates at my work place. However, I found out two days ago that I wasn't the only one.
There were three boxes of them in my lab (technically, no food or drink place, but oh what the hell. No one listens to it) as a souvenir brought by several doctors. Getting a bit hungry from not eating lunch, I sneaked upon those treasure boxes, and making sure that no one was watching me, I peeked in. First one had only one.
Ok... maybe the next one.

There was only one chocolate as well in a second box. Then, maybe.... Holding a breath, I opened the last box.

Once again, ta-dah!
There was only one piece of chocolate.

The lab's secretary and I ate two of left over chocolates, and the third one disappeared somehow overnight, consumed by a very hungry bear called Doc.
