Update on that story I've told:
My friends ****** lived in their new home, what was two months after the first encounter with ufos. The house was near an forest and they were hearing strange noises. the ufos were watching them a lot, but they didn't made a move on the ******, just stood there a long time. I have also heard, that the skin peace, what the ****** grabbed from the ufo, was soft as waffle. I don't believe it.
