Other than you know, the person being loyal, nice, and all that jazz, someone who isn't too clingy, but someone who I wouldn't make me feel awkward by not doing anything. Not just in a physical sense. They have to be someone who I can communicate with well. If we're just lingering around for hours with nothing much to do or much to say, and I can dare say that we're not suited for each other. I get really frustrated whenever I'm with someone for a few days and nothing much is happening to keep me entertained or anything. I know there are people who are shy there and not really communicative, aaand... I'm sorry. I can't be with someone like that. ._.;
Also, I don't like to constantly be told that I'm wrong, or be told information that I reaaally couldn't care less about. :v If I ask a question out of thin air, they go talking about whatever, and I give them some expression, theeen they should hopefully get the hint.
I've gotten a bit more picky over the years due to experiences. Either I suck at choosing guys or I'm shallow.
