I am preparing to pass an English test and one of the subjects in the oral exam could be describing a crime.
I was thinking about talking about a time in which I was approached by 3 underage girls begging for money, I took my wallet out and gave them a couple of coins, but before I could put my wallet back in my pocket, one of them placed a piece of cardboard over the wallet, with a sheet of paper asking me to sign something I didn't understand. In those few seconds another child reached to my open wallet that was under de piece of cardboard and stole all my money bills. I didn't notice it, I still had my wallet but later on I realised I had no bills.
Would this be a mugging? a theft without violence? I need to be very accurate when choosing the words for it because it's a difficult exam.
