I'd like some female company in my life, however I am usually reserved and don't talk much.
In social settings, I keep to myself mainly because I feel invisible so I don't bother.
I'd like to know: do women view this type of behavior as weird/arrogant/etc?

There is a CUTE Chinese young lady who works in my building but on a different floor.
We talk for a few minutes when I pass through and she always has this smile and look
But being the IDIOT that I am in these matters, I don't know if she likes me (on the smallest of levels)
Or I am just good conversation for her to break up the workday.

Any and all thoughts, suggestions, are welcome.

It really depends on the presence of the guy. I think that most people usually do judge a book by its cover, so - if the guy is well groomed, good looking, w/e, then there's nothing wrong with reservation. The best thing to do is always smile. That breaks the ice. And, if you didn't realize from the prior script - make sure you're well-groomed. I must say, however, that if you are spoken to, and THEN you are still relatively unresponsive, that can def. come across as arrogant...

Whether she likes you or not is irrelevant. Either way, absolutely NOTHING is going to happen with her unless you make the first move. Man up.

Ask her -she can either say yes,or no;that way you'll know rather than keep yourself guessing.

My opinion... Girls found that interesting may be because it's weird.
Anyway you don't have to be open unless you find a girl who deserve it (I mean you like her and she likes you), then you can open your heart safely... because if you decided to change your way you'll be hurt because your value (I thought so) differ than other way of living (I mean to be open).
Act as yourself, As it should be nothing else.
Regards.

I'd probably think you were shy,but if you're going to sit quietly in a corner,the risk is that I wouldn't notice you.

Why waste time wondering about what's on someone's mind? Ask her something about herself, and at least find out if she is friendly, flirtatious, married, single, gay, rich, poor, or a halfway trans gender, retired, serial killer, who is looking for her next victim.

Half the fun in life is finding out things you don't know, and making contact with your fellow human. You are the reserved, shy type, but at least you can pay attention, and have interesting reactions, at least do your part in the human interaction thing.

I mean who invests time, and effort into a blank wall that gives nothing back at all.

Bottom line, just do your part in any exchange, because how hard is a smile, or hello from a shy guy? Then it doesn't matter what you don't know, just know how to find out. Heck, half the people you meet don't take much prodding to open up, you just have to let them in a little.

OK, I get you. I'm lost, however, as to what to say

Understood

Ok :) I'm going to make the effort

Good luck!
