Leave the good stuff at home. As I told my sister who ignored me. She suddenly noticed, on the plane home, that a ring was gone. We found it under the seat - her finger was apparently no longer slightly swollen and it just slipped off. I wear only a watch and easily replaced hoop earrings. Why take a chance?

When we were in Naples, the Italians at the next table in a cafe, told me not to wear my gold watch. We weren't even conversing with them. Even though my watch was only gold in color, I followed their advice.
