This is true of your own backyard, too, but it’s amplified when you travel (if you have the ability to travel at all, it’s likely you’re financially better-off than many locals you’ll meet, depending where you go). Talking loudly on your iPhone in the street or piling on expensive watches and jewelry are obvious no-nos: they represent a lot of money to someone more desperate than you, who might be willing to do whatever it takes to get them.
It’s best to take only what you need travelling, and nothing of any financial or emotional value – then you’re in no danger of losing anything you care for. Get a cheap phone, bring old clothes and leave your grandmother’s heirloom ring in its box at home.
