Odd Phrases

Strange things travelers might need to know...

My step-daughter goes to school with a lot of people from other countries and, right now, there are quite a few kids from Korea at her school. She has at least one friend that's taught her some things in Korean, but she wanted to know more, so when we were out this weekend, I bought her the <A target="_blank" HREF="http://www.amazon.com/exec/obidos/ASIN/1740591666/fantasistnet">Lonely Planet Korean Phrasebook.</a> Well, we were going through some of it and found some interesting phrases. Things like "I don't do drugs" and "I only smoke marajuana occasionally". But, they also had "My period is ... weeks late" and "Stop harassing me!". How often do "travellers" really need phrases like this? What occasion calls for the discussion of drug use while in a foregin country?
I have some older Lonely Planet phrasebooks, but I don't remember seeing phrases like this in them! I guess they've updated it for the new century. Hmm, at least it gives me some ideas for updating my <a href="http://www.fantasist.net/conlang.shtml#phrasebooks">Conlang Phrasebooks</a>!
