A Terrifying Day

Just arrived in Japan and had no internet. The Chinese-Japanese translator messed up, and I almost got detained by customs. I told them I was here to travel, and they asked if I was planning a long-term stay. I said no, but the translator told them I wasn't here to travel. Then they kept asking me why I was here. I said to travel, and they said, 'You just said no, and now you're saying yes.' They suspected something was wrong, so I had to grab a pen and paper and write in terrible English: 'I want go travel to Nagasaki 10/13-17 5days but not long time she speak longtime so i say not.'
