Re: guys..
For girls, Both words and acts are needed to express your feeling. But [b]I think[/b] it's better to act. Just make him feel that you love him. Make feel him special. Show him that you care. Until he noticed it and fall in love with you.
For guys, if you want to express your feelings to someone. Do the first move. Don't make her wait. 'coz a girl can wait but she can't wait forever. Maybe she likes you too. Or she can be taken by someone. Some girls hate those guys whose "torpe". Tell them and make them feel you love them as soon as possible before it's too late.
Hope this helps. ^_^
