What do I need to be aware of when talking to an alien?

You need to carefully consider your actions and presuppose a friendly exchange. Here are suggestions that may help:

1. Try to avoid using offensive behavior and remarks. Respect each other's culture, values and dignity.
2. Try not to mention any human weapons, technology, and information that can cause damage or confusions.
3. During the communication, make sure to confirm the other party's attitude towards humans. Whenever possible, choose aliens with a friendly attitude to communicate with. If you see hostility toward you, or even toward humanity, be vigilant and inform others if the situation is out of your control.

Always keep in mind that your actions may concern humans or represent others. Your communication with aliens requires compliance with the ethics and laws of both parties.
