I think if you behave like a domestic dog, that might give a wrong impression of the humanity either. And if you start singing some of Celine Dione songs, the extraterrestrial might feel like a good opportunity to dive into the north Atlantic to fetch some extra precious stones.Off the top of my head, you need to stay still, not run or hide, and not smile, but slowly wave your straight hands palms forward until the other being would do something. Then, you slowly try to imitate what it did until it tries to imitate what you do. If you get to the point the being is trying to imitate you, you've got 90% of the success in the first contact because the being is considerate of you and recognizes you're sentient. The rest depends on what happens next, which is up to you at that point. And what happens if you don't get that 90%? That's why you need to get yourself familiar with at least some concepts of the exopsychology.

That is called "the balance" and I think it's one of the fundamental aspects of the Universe. One of the ways we can avoid war with the extraterrestrials is to become useful to them. That is an open question though as the way they might want us to become useful might not be acceptable by us. And so the politics starts ...
