...I think she means senior as in "older", or as in high school/college senior. Haha, I've joked about the latter myself, saying something like "I'm a senior, can I have a discount?" (As in college senior... *chuckle*). Of course, that's still a nice joke.
Well, going beyond the usual (I would almost say universal) qualities of nice, respectful, considerate, etc... I find myself being really attracted to a guy whose spiritual beliefs are very similar to mine, moreso than anything else. There's just something about being on a similar philosophical level about things that just really makes me happy. Of course, the problem is that very few people my age have spiritual beliefs similar to mine. The vast majority of them are either not very spiritual at all (the case with my current boyfriend) or follow a religion that I don't. Since I am a very spiritual person myself, I always see this as a sort of barrier in a relationship.
Similarly, and I know this sounds wrong, but no matter how pure of heart a guy may be, if he is far less intelligent than I am, it's a problem. I know this from experience; my first boyfriend was possibly the nicest and sweetest guy I've ever met, but he wasn't exactly the brightest. This actually led to communication barriers between us; he often had a hard time understanding me and what I was talking about, and we always seemed to be on completely different levels of understanding on most conversation topics. This, in addition to the fact that he wasn't all that good-looking either, outweighed the sympathy I had for him and dampened any passion I had about the relationship.
I am also really attracted to guys who are more of the quiet and sensitive type, as opposed to the tough or outgoing type. I can handle a little of extroversion in a guy, but not to the point where it completely masks their more introverted side. I guess this makes sense, as I've seen relationships between an extrovert and an introvert (my own now-divorced parents being one example) end badly or become challenging in the least. I guess given these above factors, the most important thing to me is that he's on a similar wavelength as me on most things. And by that I don't mean the same interests and hobbies; I just mean their general nature. You know, psychology and whatnot.
Appearance-wise, I prefer thinner and more nerdy-looking guys, or ones with an almost effeminate feel to them (the latter goes for their personality as well). The latter explains why I often become attracted to guys who turn out to be gay. Long hair is also a huge turn-on for me; in fact, I've expressed dismay at a couple of long-haired guys I knew who cut their hair short several months after I met them. I also like it when a guy has a good fashion sense, which apparently is rare in today's world.
Taking all of the above into account, I'd probably be strongly attracted to hippies. XD
