Here's what I am thinking at the moment, and by the way, the question applies only to single, free and available people... I believe it's all about culture. If our culture tells us that it is inappropriate for a girl to make the first move or to suggest anything, then a girl is left to suppress her feelings for a guy. This was the culture that I was brought up in; although there were times before that I was left thinking if I would have felt better about myself if I allowed myself to be more open about my feelings. I guess it worked better for me that I didn't because my feelings cannot be trusted at that time yet because they're still unstable. With other countries, though, they say it is even okay to ask the guy for a date. And girls are not even offended if they are rejected.
Well, anyway, our ability to handle ourselves with men around would somehow change as we grow mature.
When we like someone, we can still show the person that we do and can somehow drop a hint that we look forward to getting to know him better.
I am not a relationship guru but here are my ideas on how we can let a person know that we like him and/or how to get a guy to get to know you better:
1. Look at the person in the eye when you talk and show some sincerity.
2. Be interesting, just as you are. You don't have to act differently. Just try to repackage yourself. I can explain it better this way – If you are going to present a video that the person has not seen yet, he would be skeptical if that video is a good one. So, what do you do? Choose a good 'thumbnail' for that video. Something that you think might catch the person's attention. Highlight the interesting part first but remember not to give everything – just the thumbnail so the person will have to go watch the video until he finishes the full version. Does it make any sense?
3. Invite the person along with your other sets of friends for some peer activity that will allow both of you to get to know each other. Just do some wholesome fun. Don't think about anything that has to do with wine and getting drunk. They're not going to do both of you any good.
4. Try to be the person with no hang-ups. Even though misery loves company, you don't want to end up miserable with a miserable person. Be the positive person (speak to people, smile at people... blah blah blah) that you would like to be.
5. Don't be someone too intimidating for a guy. Don't give a wrong impression that you're too beautiful to be dating anyone.
Is there anything that I'm missing here? Feel free to comment. :-)
