Here are some tips on getting a shy or quiet girl, please read closley but try not to over read it.
1: Make her laugh, she loves to laugh and have a good time.
2: Don't force her to open up right away, get to know her, you may be surprized (in a good way).
3: Smile, she wants to know if you're happy too. But don't fake a smile.
4: Don't be too silly, or too serious, as said before, she wants to have a good time.
5: if she rejects your offers, then it means she may not be intrerested in you.
6: Hang out with her, if your still in school, then that's a good oppertunity to every once in awhile hang out with her.
7: Be yourself, because if you don't and she finds out your pretending, she won't like that.
8: take things slowly, including friendship, romance, ect.
9: Make sure you gain her trust, she'll enjoy that very much, but if you break it, you'd be lucky to get her back.
10: become friends with her before dating her, she'll feel more comfortable with being in your arms.
11: Once you've got her, it wouldn't hurt to every once in awhile tell her that you love her and give her a gift. But not all the time because that would be overwhelming.
12: Make sure it's ok to kiss her and show affection to her in public, some girls don't like that!
13: listen to her, and when she's done talking respond. It's ok to tell the truth.
14: flirting with other girls isn't ok, even if it isn't in front of the girl you love gossip can get around, and could make her feel unspecial.
15: You don't have to be a gentlemen all the time, if she's a pervert on the inside then be perverted. If she's kind and caring then be kind and caring. Just remember WHO YOU ARE.
