Living alone is definately scary at the first go..But then one learns the tight rope walking.I am an International Marketing Manger and need to travel abroad frequently.Earlier I used to stay in hotels.Five star hotels are safe , howver still i used to ensure that i kept one light switched on , my mobile kept besides me, and the door locked properly.Now , I have moved to an apartment , the same rules goes on.Do not go to deserted areas and speak to strangers and let them realise that you are new to that area.Always take the help of policemen.It is not like India where Police is the main cause of fear.In the end , it all boils down to how you carry yourself.
