Point 1 in the quote. If you take a blond haired boy everybody, and I mean everybody, will want to touch his head. For some reason it is considered good luck.

Point 2. Definitely expect to bargain and don't be disappointed if you are not very good at it. Bahasa Indonesian is very easy for simple words like the numbers that you need for counting. Don't forget to say please and thank you. Also I found that I had no problems with accents after learning the basics out of a book.
