romance

You are definitely right. Girls are full of ironies. Most of the time they want to keep you guessing on how to approach her. They tend to keep their age secret because men usually seek younger girls but they get disappointed when you forget their birthday because that is a special day for them. They somehow expect that if they are special to you, you will NEVER ever forget that. When they said no, sometimes it means yes. When a problem arises and they said "I'm ok!", don't leave them because they are not. Since generally, girls are good in nonverbal language, they expect their partners can read the signs too. Some of the girls think that if they are important to you, they expect you to listen with their hearts. They really can drive you crazy! But actually they are very easy to deal with. Just don't take them literally most of the time. They just want to be pursued.

sounds too funny, but it is a fact... i am a lady and for me yes, my birthday is too important if somebody forget that i will be sure that person did not make any value for me and does not love me at all..

Yes, they are. Just give them some time to grow up, then they will not be funny anymore. As you know, girl is always a girl, youthful immaturity is not uncommon among girls.
