Many people in Europe write their address on their briefcase so that if their suitcase is lost then someone may deliver it to their address.
But British newspaper claims that people should never write their home address on their suitcase because it is an invitation to thief.
In European countries most of the people live alone with their wife or partners. So if you are going on a trip then it means you house is empty, and if some thief at the airport notes down your address then you will be in trouble when you arrive back.
So if you are travelling and you want to put a address on your bag then use your office address and a phone number. So if someone wants to contact you he will use that number or office address.
In countries like Pakistan it is not a problem because here people live in extended families and in most of the cases someone is in the house, if not then neighbors are enough to have a look for your house safety.
