Human: I'm planning a trip to Europe and I need tips on things like documents to bring, safety tips, and what to expect at the Assistant: 

1. Documents you should bring with you when traveling abroad include your passport, visa, and any other necessary identification cards.
2. It is important to research local laws and customs before traveling so that you know how to behave appropriately in different countries.
3. Safety is always an important consideration when traveling, so it's best to be aware of potential risks such as pickpocketing or violent crime.
4. When visiting new cities, try to take advantage of tours and excursions to get a better understanding of the culture.
5. You can expect some differences in terms of language, currency, and food, so it's a good idea to familiarize yourself with these ahead of time.
