I am feeling excited and nervous

Yes, I am feeling excited and nervous. Why? My parents have found out an alliance for me. On christmas day when I landed in my native my parents have me this pleasant surprise which immediately aroused excitement in me. My dad showed me her photo and there was no reason for me to dislike her. She reminded me of my sister, she is fair tall enough for me. This is all I could infer from that photograph. But my parents seemed to be convinced about her being a good companion for me. Not only my parents but also most of my relatives are all talking good about her and her family.

Now after one day when I am free of talking with anyone (I am travelling to meet my sister) I am forced to think about my future and I am getting from the excited state to a little nervous one.
What had I in my mind about my companion, well I do not know how to say. Because I had not defined a companion for myself in any way. I like to let my companion think of what she would like to be; and not to impose any of my beliefs on her. But I have some small, very small expectations of what will make a good companion for me. I may have formed this from the women I know well, my mom and sister. Almost every man arrives at the conclusion of choosing his partner this way. Some knowingly, some unknowingly. I have inspired from my mom a alot and her qualities may be the first stop for me to define my partner.

I am going to meet her for the first time day after tomorrow, let me see if I can reduce my emotions and present myself as a normal as I usually am.
