Knowing at 35 yo that I had a 20 yo half-sister on a different continent was really a surprise. My father worked for 15 years for a British oil company in Brazil and only now I found out he spread his seeds there. I went to Brazil to meet my sister but it came out completely different from what I could imagine. She didn't wanted to ear about it, she only wanted to make money so that was I gave her in exchange of what she had to offer.
