Article: Several overseas trips with the family have taught us that they can be rewarding, but you always have to be careful of pickpockets. On a lovely visit to Paris an encounter with a pickpocket gave the would-be thief a little more than he _ While walking down the famous Champs Elysee, I was astonished to feel someone unzip my handbag and remove my purse. I turned to glimpse a young man turning away and pretending to be absorbed in the mouth-watering contents on display in a bakery window. Being only a teenager at the time, I had no idea what to do. So I tapped the young man in question on the shoulder and said. "Excuse me can you please give me back my purse?" Of course the pickpocket had no idea what I was saying (and didn't want to know) and proceeded to shrug his shoulders and basically say (in French) "I don't speak English"? Meanwhile my Mother (a Scotswoman with a bad temper), came to see why I had stopped walking and what was going on. When I informed her of the situation she lost control and started yelling at the thief who still stood there making gestures in French while a crazy Scotswoman harangued him. At this stage we were starting to attract onlookers, and when my Mother started hitting the young man with her handbag the would-be thief decided it was time to get away. Luckily, amid all the disorder the thief lost his control of my purse, and as he made a break-for-it, my purse dropped to the ground! I quickly snatched it up and for the rest of vacation we walked around with our handbags clutched against our chests!
