45. Be smart and very careful

I once saw three muggings in one day in Rome.
Two were by gypsy children, one was a Vespa grab-by.
Fortunately I was not a victim. You have to be very aware of your surroundings and very sharp with your objections.
They prey upon people who are blissfully engaged in being in a foreign exotic space.
Hate to admit it, but I defended myself and spouse with force (use whatever you are carrying as a defensive weapon) - that gets their attention quick and they'll move on to the next vic.
My three muggings day was many years ago - we have since been back a few times to several European cities and areas without any incident.
If you can, avoid big crowded cities in favor of the smaller towns and villages which are much nicer anyway.
