@Fa5t3r - In some ways I agree, but there is one thing that is very important to remember when trying to make friends with people if you're overseas. Safety has to come first and you can't trust people you don't know well, especially if they have a different culture. I'm not saying different cultures are untrustworthy, only that it's difficult to know if you mean the same thing when you say or do something.
This goes double for women. I've had encounters where I thought I was just being friendly and the man involved thought we were flirting and tried to push for more. This can be terrifying if you're on your own.
My best travel abroad tips always center around the idea of being flexible and friendly, but not foolish. Don't take anything for granted.
