What was the most impressive thing you experienced when you were eighteen?

18 years old, I happened to have followed the school's allocation out of the internship, it was my first time to leave home, leave parents alone to another strange city to work, fortunately at that time is to follow the school, there are a lot of students know. I remember the first time into the factory work, everything is full of interest and curiosity, but also from that time onwards to know the hard life, the hard-won money, from that time onwards to understand, the original in the school is really the happiest time for us.
