I just joined this website today not to sure i have too much to offer - but I have been to alot of Aia alot of times - and I find it is very helpful to have purpose - the way you walk - have a plan of where you are going and what you are doing for the day - learn a bit of the language - and be totally confident whatever you are doing. You must LOOK around at all times. But of course this applies to where you live too!!!, always be aware of your surroundings. Don't be conned. If ppl want to take you to gemstores or learn English better - just say NO - you have other things to do. It is common sense - you wouldn't go looking at some 'gem store/mine' at home would you. Maybe you would - but rest assured - if someone has to contact YOU about buying something - it probably wasn't what you wanted or needed anyways.
