The Profession

You decide that to be on the safe side you better hide. You look around for an object that will conceal you and find the exact thing you were looking for. A bin. You lift it off the ground so it doesn't make a scraping noise on the ground, you walk over to a wall and you drop the bin quietly in front of you concealing your whole body.
The man - who you now can distinguish as a Town Guard - walks by you again. You think about how easily you could take him down, but remember the discreetness you have to use, so you leave the man alone.
