Would you steal an abandoned boiled sweet?

I saw it there, sitting on a table in the staff room at school, at 4pm.  A boiled sweet (a Murray mint, for the initiated), alone and unclaimed.  I looked at it.  For a long time.  Then turned my back and went back down to the office.

At 5pm, I had to come back up to do some photocopying.  The boiled sweet was still there, in exactly the same place.  (Surely if someone really wanted it and had mislaid it, they would have come looking .....)  I did my photocopying.  Then I looked at the sweet again.  For a long, long time.  Then turned my back and went back down to the office.

At 6pm, I had to come back up to check a duty rota before I went home.  It had been three hours since I'd had anything to eat or drink.  I was tired.  I was weary.  My mouth was dry.  And, as I stood and looked at the sweet, everything I'd ever believed about morality was crumbling.

At 6.03, after much consideration ....

I'll leave you to guess.
