Family business

My brother is coming to Frankfurt on Tuesday for a conference, and he actually sent me an Email to ask whether we could meet. It was kind of a surprise (to say the least), and I am really really happy and excited about it. Last time we saw was... hm. I guess it was Christmas 2006. And last time we had any contact was about a year ago, I guess. So it's been a long time. And me moving away was not, I think, the main reason for not keeping in touch. I don't know. Sometime during our young adult age, I think my brother came to look at me as being kind of - hysterical, that word just keeps popping up in my head. Though he never said anything of the like. It's just the way he looks at me, and his reactions to the things I do, the decisions I make about my life, the paths I choose to go, all that seems kind of bewildering to him. We used to be very close. I mean of course we would fight a lot, but growing up, I was really hanging out with him and his friends most of the time. I guess I was what one would call a tomboy.
And at one point, it was more or less when I was going through puberty and he wasn't (I think he had his kind of puberty as rebellion kind of thing only in his early twenties), I had a strong need to des-identify myself with him. A strong feeling of repulsion, of annoyance about him. I thought he was boring and all that sort of stuff. And I guess when I was ready to "go back" to our relationship again, he had moved on. And since then it seems that he has never been that interested again in having a friendship with me. So I lost him. Or I lost our closeness. And it still makes me sad. I miss him. Terribly at times. But it seems that he has his own life now, and I don't seem to be an important or big part of it, and he doesn't want me to be.
So I'm glad that he wants to see me next week. I hope it is not because he has some "big" thing to announce (like his wife being pregnant or something), but just because he wants to see me.
