It's a two way street. Some people need to go to some completely different place to relax enough, and some other people bet on tourists being relaxed enough.

I even remember that kind of effect from school, during school time I would always get into fights with kids that I was happily hanging around with in the holidays.

Tourist hunters are different. They know France is, for some reason, the first worldwide destination and flock here to steal your wallets. They'll be on the steps to the Sacré Cœur to tie a bit of string around your wrist while a comparse grabs your wallet, your keys, your underwear and your toupee.
