Be prepared
Prepare some topics for any situations--e.g., the weather, your major/school, the Netherlands.
Be engaging
If you're not enthusiastic about your topics, no one else will.
Ask questions to make that person part of the conversation.
Be willing to tell
When you are engaging the other person, the person may have questions. Be willing to answer them, or come up with reasons why you don't wish to answer.
Be friendly and courteous
Smile. You don't know the person, and in all likelihood, you may not see her/him again. So, be nice and friendly. Leave a good impression. Say "thank you, goodbye".
