I'm really bad at describing people, so please bear with me... This is a German friend who I met while I lived in Austria (if that is useful )
I am not sure whether he is an I or an E. But one thing that I know about him is that he values family life. It seems that he only spends time with his family members, whether it's traveling two hours to be with them on the weekend or going to concerts with them. He is not secretive about his them either and can be a bit judgmental. He openly shares with me his frustrations and dreams, but does seem to get a bit aggressive with other males and authority.
He remembers every single detail that I tell him. It's actually a bit odd. Something that I told him several months ago, he would bring it up again. And once again, he doesn't seem to be ashamed of his feelings and surprisingly, doesn't get frustrated when I don't express myself emotionally. So I am assuming maybe an FJ? He works as an architect and models boats or ships (I think... Ahaha). He doesn't talk much about his job, but tells me he often feels underappreciated.
He's really big into music, plays the guitar, etc. He seems a bit embarrassed by his musical talent (even though it is very good), but he's not afraid to play things for me. I really do not think that he is shy at all, just reserved.
IDK what else to add
