Boa noite, Senhor. Como esta'?
Sua fotografica e' muito lindo. I've lost most of my Portuguese abilities simply from lack of use, but my dad was fluent, from hearing it in his home. Your English is just fine.
I'm just speculating, but it does sound like the contactee may have some psychological issues, and perhaps the issues may be secondary to abductions, or meetings with ET's? It can be terrifying, and the repeated terror could cause post-traumatic stress disorder. That doesn't mean that he's not being truthful about the E.T.'s showing up, as you already said did happen.
It would be great to get him here to tell his story himself. Thanks for sharing this story.
