It's 8 o'clock in the evening outside, you're already getting ready to take a shower when your little brother Miron comes up to you.

• Sister, I need help.
  -what already?
• For the fake I need leaves, chestnuts, moss, well, you get the idea.
• Seriously?! Couldn't you have told me earlier?!
  -Well, please...
  -OK.
  You went back to the room, threw on something warm, took your bag, package, phone and all sorts of little things.
  You went outside and headed to the park. Fifteen minutes later, you were there and started looking for counterfeit jewelry. A short time later, a tall man approached you. He was wearing a uniform with the word "OMON" emblazoned on his chest. He clearly suspected you of being some kind of drug dealer or, conversely, a buyer.
  -Citizen, what are we looking for here?
